The Night Boeing’s 747 secrets ran from a restaurant in Paris hidden in napkins – Jalopnik

Imagine this: Paris, in the late 1960s. The Cold War is anything but cold, and the sky is thick from a cool, weird Citroën DS and Chanel No. 5. Joe Sutter, chief engineer of the now almost disappeared Boeing 747, goes to a dinner meeting that feels more like a scene from a bond film than a business trip. His eating mates are not airlines or aluminum suppliers; They are a delegation of aviation engineers from the Soviet Union.

This was also not a back-alley deal. The US Department of Foreign Affairs had asked Boeing to act technical information with its primary global Nemesis of that time. The whole thing was a top sanctioned by the government on the neutral ground of a Paris restaurant. It raises the question, why on earth would Uncle Sam ask for one of the most important companies to transfer technology to the competition? The answer, it turns out, was an exchange of high bet, a desperate need for a rare metal and a lot of vodka.

Dinner in Paris was not about promoting international goodwill; It was born from mutual Spijkerb biting despair. In the late 60s, Boeing juggled with two gigantic projects that threatened the company too bankrupt. First was the 747, a gamble at a Moonshot level to build the world’s greatest passenger beam in a period of 28 months. The other was the doomed Supersonic Boeing 2707, the planned response from the United States to the French-British Concorde and the Soviet TU-144 transport.

America’s Supersonic Transport (SST) program had a huge problem with the 2707. To fly with the target speed of Mach 2.7, his hull had to be made of titanium to withstand the intense heat of air friction. The problem? Boeing did not have the expertise to manufacture titanium on that scale, but guess who did that? Yup, the Soviet Union. Thanks to its enormous reserves and advanced space program, it was the world leader in titanium production at the time.

In the meantime, the Soviets had their own problem with Jumbo-Jet-Sized. Their initial designs of a 747-Dupe were conservative, but they were especially stunned by one thing: why Boeing mounted his engines on pylons under the wings, while Soviet designs preferred to put them on the rear hull. This was the question they brought to Paris. The stage was set for a classic quid pro quo, with Boeing’s president, Thornton “t” Wilson, who orchestrated the trade.

The dinner started with a targeted intelligence operation, while Boeing’s SST expert Bob Withington grilled the Sovietsieurs on the complicated art of titanium manufacturing. The Soviets enthusiastically answered every question openly and in detail. Because the Boeing team got what it needed, Wilson Sutter gave a direct order to stop nothing. What followed was a spontaneous master class in the design of the plane, outlined on fabric napkins and the tablecloth itself because no paper was useful. A critical supervision if we are honest, but perhaps both parties also thought to bring notebooks.

Sutter explained the genius of the pylon design mounted on the wing: it caused bending help and made the engines safer and easier to maintain. When dinner ended, the Soviet delegation carefully rolled up the inked linen and took a paradigm shift in the aviation philosophy home.

The impact was clear. The Ilyushin IL-86, the Jumbo Jet of the Soviets, shortly thereafter underwent a radical redesign and threw the layout with rear motor for an underwing configuration with four engines. However, it seemed suspicious as a 747. However, it was not a direct copy-the IL-86 was ultimately ruined by his terribly inefficient, outdated engines, which shows that all know-how in the room does not guarantee a success. However, the fundamental design was a direct consequence of the secrets that ran from a restaurant in Paris, tucked away in a handful of napkins.
