Dear Father:

I hope this finds you well, because I am going to be so brief that you will probably be very disappointed in me. Please don't be, as I have to save my energy in order to sell blood to pay for my phone bill this month! (If Nationalist China ever has a working phone system, I will have paid my share!)


Your Loving Son,
Reggie

PS: Ronnie's exams went fine, but I'm sure she told you that herself. First year Law, done!

A Technological Appendix to Postblogging Technology, March 1950: We Need To Talk About Martin


Martin B-26 Marauder: The "Baltimore Widomaker"


On 29 August 1948, Northwest Airlines Flight 421, a Martin 2-0-2 crashed near Winona, Minnesota, killing all 37 aboard. The plane went down on the slopes of a steep gully (I didn't know they had those in Minnesota!) and body recovery was extremely traumatic to would-be rescuers. 

When an observant captain asked that another Northwest Airline 2-0-2 with similar flying hours be inspected for handling issues that same day, attention was drawn to a stress failure at a wing skin-spar joint, and the cause of loss in the Winona accident was determined to be a wing falling off due to stress failure. 

The appellate judge does a good job of summarising the technical details in the 1955 judgement that let Martin off the hook for  negligence. (Northwest oversaw production in detail, so no one principal was more negligent than the other.) Martin adopted an high-strength aluminum-magnesium alloys that was relatively new to the aviation industry due to its high notch sensitivity. It had been used with great success in the Mitsubishi A6M Zero, and was a definite late-war fad, although so were the stress-corrosion related groundings of the late Forties, and considering the way the Zero was used in service it's not hard to believe that stress corrosion problems were overlooked. 

Call me lazy or call me a victim of industry capture of aviation journalism, but I was surprised to read, last month about the 7 March 1950 loss of Northwest Orient Airlines Flight 307, another Martin 2-0-2, while trying to land at Minneapolis. Although the crash was determined to be the result of the pilot losing ground reference while landing in a snowstorm, the actual cause of the crash was a seventy-foot flagpole, causing a section of the left wing to detach. Obviously no-one is asking that an aircraft wing survive a collision like this, but the 2-0-2s had been grounded, at great expense to the airline while the problem was being fixed, and the suspicion has to arise that the fix had been less than completely successful. 

We can also, of course, reasonably ask why there was only a pilot and co-pilot in the cockpit at the time. CAA regulations did allow for this, and it was a pretty straightforward implication of the idea of a "DC-3 replacement" that the Martin 2-0-2 be operable by two crew. Tens of thousands of DC-3s had landed safely in similar conditions across Canada and the United States, but it has to be said that airlines picked approach routes that didn't have 70ft flagpoles on them. The Minneapolis approach route didn't have one, either, but the plane was off course, if only by a little more than a mile; which would seem to be at least as important a factor in the crash as the fact that it was too low. 

So much for one accident involving a half-full plane. It  turns out that a Northwest Orient training flight crashed near Almelund, Minnesota, on 13 October 1950, with six casualties; that Northwest Orient Flight 115 crashed near Butte, Montana, on 7 November 1950, with 21 fatalities; that another Flight 115 2-0-2 crashed near Reardon, Washington, on 16 January 1951 after unexplained loss of control in flight. This last had only ten people on board, which suggests that the news was getting out to the travelling public, although that didn't stop a strange Japan Airlines/Northwest Flight 301 crash in Japan with 37 fatalities. Rearden was the last straw for Northwest, which sold its remaining 2-0-2 fleet to Allegheny Airlines. Since Allegheny (and Transworld) operated the 2-0-2 happily for another ten years, either the problems really were ironed out, or it was all just a terrible series of coincidences. 

The problem is that in 1950, Allegheny's fine record was in the future, and the Glenn L. Martin Aviation Company looks really, really bad. While it's not the only company saddled with a dangerous airliner in this era, but the stunning series of 2-0-2 accidents is hardly going to help a company that operated, after all, in what was practically a suburb of Washington, DC. People are going to talk!



It's also not the the end of the story from March of 1950. We've still got an (undersourced) internal, blistering report on the Matador/Mace program, already prefigured in Aviation Week's recent lament that no-one could possibly expect industry prime contractors to master all the science involved in a guided missile. And although that report is still several years away, it turns out that the guided missile that's setting records of reliability and usefulness down at White Sands according to various anonymous sources is the Martin Matador.

The Bishops' Sea: Who Is This "Henry" Guy, Again?





The anonymous author of the Wikipedia life of Marinid Sultan Abu al-Hasan Ali ibn Othman (1297--1351) seems to really like the way that this 1930 German textbook map contextualises the affairs of Ceuta and Gibraltar. Sultan Abu al-Hasan captured Gibraltar from Castile in 1319, and then tried to use it as the springboard for a more ambitious campaign against Tarifa, aiming to restore a Marinid Moroccan presence in Iberia, provoking an ambiguously enthusiastic response from the Nasrids of Granada and the last, successful defensive campaign of the Reconquista. 

My question for this week is whether it actually contextualises this:

I'm not trying to ask a profound question here. The Boas Esperanca is no Kon Tiki or Olympias. It's a pretty good reconstruction of a well-known and historically important ship type. We may not know exactly what a Fifteenth Century caravel looked like, but this is fine and it's surely close enough for counting. There's really no significant questions about the vessel itself. But this is, occasionally, a blog about the history of technology, and one of the more important current set-piece arguments about the role of technology in history is that it was invented by one Prince Henry the Navigator. 

"The caravel (Portuguese: caravela, IPA: [kɐɾɐˈvɛlɐ]) was a small, highly manoeuvrable sailing ship developed in the 15th century by the Portuguese to explore along the West African coast and into the Atlantic Ocean." Which is bullshit, in that it's just a big old fishing boat, but also pretty amazing considering that biographers of the Portuguese prince have been spending decades purging the public sphere of the idea of Prince Henry as a teacher and master of the arts of celestial navigation, teaching the sciences of the sea to a generation of young explorers at an ascetic academy on Point Sagres, opening up the world to European--- 

--So, yeah, anyway.  Point is, the moment that Nineteenth Century notion is thrown on the ash heap of history, it sneaks back in again through the back door, an obvious nod to a narrative of technological determinism in which you need the services of a great man to exogenously introduce the necessary technology to change all history. 

Why not? It's how it works in Sid Meier's Civilisation! Navigation takes a ton of Science points, but the moment you have it, you can dump 600 gold into a caravel and, if you're lucky, have enough luxury goods flowing back to your ports to bring your empire back to positive happiness in a turn or three. 

Some pushback, even if not dispositive, seems warranted. And you'll probably guess from my choice of two really, really bad reconstructions that I have an axe to grind, and that "pushback" is likely to turn out to be a hatchet job. Long time readers probably won't be surprised. Anyone else, I'm just being upfront. Though not so upfront that I can't do a driveby on the Trireme Trust!

Postblogging Technology, March 1950, II: Under the Hurtling Moons

Dear Father:

Please thank Mother for the care package, which arrived via Uncle George yesterday. I am not going to be able to write her before Friday, as direct after I mail this, I have to go down to the capital to have a very important meeting. I hope I will be declared persona non grata and sent home on account of my family feuding with Gitmo's family. My enthusiasm for this gig knows no limits! Tell Mom not to worry. He's not even shooting his real enemies right now, and  I'm a serving US Navy officer! But I'm probably just going to get another argument about how the Koumintang needs more planes to parachute more agents into the South. I'm at a loss as to what they expect to achieve from all of this. The only argument in its favour that I can think of is that some of it ends up in Chennault's pocket.

Ronnie is trying to recover from moots and prepare for final exams all at the same time. Those are , hard things that law students do. So she'd have no time for all those magazines even if the public health office (no joy!) saw fit to release it. And they're being extra careful now that diphtheria has broken out again down south in San Jose. 

In the mean time, I'm trying to relate. In engineering, all you have to do these days is learn the solutions to the Three Partial Differential Equations You're Allowed To Put on the Exam. Some of my colleagues couldn't quite grasp that, but I honestly don't know why we aren't all on the honour roll. All engineers really need to know is how to punch out a mule, after all. I tell myself that that's what lawyers say about the first year law exams looking back, too. Maybe it's all for the best, as the more I think about it, the more I'm reminded that all the engineers are going back for their doctorates these days. I'd finally have an excuse to learn tensors!


Your Loving Son,
Reggie

PS: I notice that I've got a bit mixed up about where I am with Aviation Week. Well, that's tough. It's too hot to work and the custodian is outside waiting for me to go out for the evening so that he can update the cottage for summer. I don't think he's allowed to knock off until he's done, and it's already past 4.

Postblogging Technology, March 1950, I: Go Sane!

Dear Father:

I'm sure you're not suprised to hear from me again.I'd say something sarcastic, or angry, but what is left to say? Palo Alto's public health officer is apparently allowed to lock himself in his house for as long as he likes (although the note on his office door at Memorial Hospital has been changed so that it doesn't mention the date he started working at home any more, so I guess that's progress of a sort). If you don't get your magazine subscriptions, then maybe you should stop being so cheap and resubscribe! I'm sure Time would like that!

I'd tell you more, but I've not much to say. Things are a bit tense here right now, and I've been showing the "better part of valour" at Uncle George's urging. I can't tell you how grateful I am that he's decided to stay in Hong Kong "for the duration of the filming." Quotation marks because I thought that your average Hong Kong movie takes about fifteen minutes to film, but I am not going to argue that he should be moving on when I feel like I need eyes in the back of my head.

The Plantation of the Atlantic: An African Reconnaissance

A boat launching in the Banc d'Arguin National Park



At the risk of repeating myself, it's worth restating where this investigation has been going. First of all, I have Lameen's challenge to think of a West African Age of the Reconnaissance, which turns out to be exactly right. And, second, we have the challenge of taking Morocco as a key actor in the European Reconnaissance seriously. 

It is an old truism of the earliest "Reconnaissance of the Atlantic" that the Portuguese effort that eventually led to Vasco da Gama rounding the Cape and reaching India, began as an attempt to bypass Moroccan control of the northwestern terminus of the trans-Saharan trade in sub-Saharan gold, slaves and naturalia. Going a little further, Peter Russell suggested in 1994 that this effort was, on the one hand, an extension of an attempted Portuguese continuation of the Reconquista into the southernmost portions of the old Roman Diocese of Hispania, which is to say, Morocco; and on the other, a defensive measure against Castilian efforts to secure the defection of Hispano-Lusitanian grandees with opportunities to crusade.  

All of this is interesting, but would be less so if, in fact, the Portuguese had just arrived on the African shore in 1405. In reality, the city of Ceuta has traded hands between Hispanic and Moroccan regimes so often that I doubt anyone can keep track, and, by extension, Hispanic and Moroccan regimes have their hands deep in each others' pockets since at least sub-Roman times. Therefore, Prince Henry's involvement in Morocco has as its mirror image, Moroccan interest in Portugal. Or, to put it another way, that it is all one political realm, and Moroccan politics have to be considered alongside Hispanic.

It is probably also worth noting that the core period of Henry's African adventure coincided with the period in which Henry's brother was being held hostage in Fez for a Marinid restoration in Ceuta. Ferdinand surrendered himself in 1438 and died in 1443, a period spanning the first half of Afonso V's difficult minority. During this short period, a series of expeditions along the coast reached the Bay D'Arguin and as far beyond it as the mouths of the Gambia and the Senegal. Henry, withdrawn from politics to his villa at Sagres, remained an entrenched opponent to any scheme for the redemption of the Infante Ferdinand, while patronising the geographical, and, perhaps, naval architectural sciences. 


Note all the little Portuguese enclaves down 
the coast. 

So any understanding of this adventure needs to focus on the political axis between Fez and Sagres. This much, should, indeed, be obvious. There is, however, that traditional blindness, or to be more charitable, professional unwillingness to overextend, that puts Morocco in a different category from Europe, drawing the line of political history at water's edge. There is also the foreshortening effect that makes far off countries seem smaller and more homogeneous than they would seem if we took their politics more seriously. Morocco, in particular, is a very big country. The Almoravid/Almohad imperial city of Marrakesh is 500km south of the Marinid/Wattid capital of Fez, and even a Martian would, when it was put that way, expect a north-south rivalry. It is, moreover, a rivalry that one can easily visualise as producing a kaleidoscopic variety of potential alliances. From the perspective of Ferdinand's uneasy custodian, the vizier Abu Abd Allah al-Sheikh Muhammad ibn Yahya, not only Portugal, but also Castile, Aragon, Tlemcen, Marrakesh and the sub-Sahelian states all had to be taken into account. 

 And for anyone from the marginalised North, South, East or West of any given polity, attention will be on the marginalised, the political interest denied its legitimacy by the simple expedient of grouping it into the larger state. Morocco had just been through an extended period of government from the south, by the Almoravids and the Almohads. I'm going to link to that classically bloated Hollywood epic, El Cid, again, just so that the reader can appreciate the way that even the comparatively heedless visual politics of the 1960s biopic could read the Almohads as a threat to northern Christians and Muslims alike. (And a reminder that mask politics is not new.) It's unfortunate that it was the Almoravids who sometimes trace their origins to a ribat on the island of Tidra in the Bay d'Arguin, but given that the Portuguese did not just happen to arrive in 1405, full of wide-eyed innocence, on the North African shore in 1405, the arrival there in 1443 of Nuno Tristao, and his subsequent attack on a village on the adjacent island of Arguin, has, or ought to have, resonance. As much as Christian slavers were an ominous novelty in African affairs, small communities on islands in the Bay of Arguin were an established threat to northern regimes.

A Technological and Hometown Appendix to Postblogging Technology, February 1950: The First Broken Arrow

I don't find any pictures of Port Hardy Airport's legendary derelict B-24.


It shouldn't really come as a surprise that the USAF lost three nuclear weapons in Canada in the early 1950s. If there's anything this blogging has brought home to me, it's that the aviation world remained just astonishingly lackadaisical in 1950. I didn't think anything was going to beat Bermuda Sky Queen or the BSAA saga, but then I noticed that no-one was noticing the four major KLM accidents in the two-and-a-half years beginning 26 January 1947. KLM is not an airline that occurs to me when the phrase "safety problem" comes up, perhaps because no-one brings it up. 

It's worth reflecting that the air search component of the Broken Arrow incident I will be discussing today was supplemented by aircraft called off the search for Douglas C-54 Skymaster 42-72469, which went down somewhere over the Yukon or British Columbia two weeks earlier with 8 crew, 34 members of SAC trooping to Montana, and someone's wife and baby (Joyce and Victor Espe, wife and infant son of Master Sergeant Robert Espe of 57th Air Installation Squadron.) The biggest air accident in Canada to that point and still the largest unexplained disappearance of American service personnel, you wouldn't even know about it from the aviation press. the much-urged policy of not mentioning passenger aircraft accidents in hopes that they would go away appears to have been implemented at some point in late 1949, and there you go. 

The same lackadaisicalness is seen in persistent reports that B-36B 44-92075 went down on Vancouver Island. The distinction between "Vancouver" and "Vancouver Island" seems to throw people for a loop and justify all sorts of geographical confusion, but the actual location of the wreckage, 6300ft up the side of Mount Kologet in the Nass Basin in the far northwest of British Columbia, is of very large significance to the story, and so is the island from which the survivors were recovered, Princess Royal Island in the central coast region, or, as we now say in a slightly twee way, "The Great Bear Rainforest." (Having given up on logging most of the region, we've settled for trying to attract the rare tourist who needs something more than 120" of rain a year to justify some adventure tourism.) 

On the other hand, the search headquarters was set up at Port Hardy, at least some of the survivors made it there before being hurriedly extracted to America, and for the first day of flying, the air search component was confined to the north end of Vancouver Island, because it was the only place where the weather allowed flying. Since Port Hardy is just a hop, skip and a bum-slide over from Port Alice, more than justifying slapping a "Port Alice" tag on this post. I had no idea that my hometown was so closely (that is, not closely at all) associated with a Broken Arrow incident, and, for that matter, the first one.
