Why We Lost The Vietnam War

Any design Boeing had was more luck than judgment.

How so? Boeing had more experience designing and building large
pressurized
aircraft than anyone else in the world at that time, perhaps more than all
other manufacturers combined.

When the results came
out it was simple to avoid the problems.

But they avoided the problems BEFORE
the results came out. They avoided the
Comet's problems even before the Comet's problems surfaced.

What strange logic. How would they know what the problems were until the
Comet investigation? Were they good guessers? This is what you said "They
avoided the Comet's problems even before the Comet's problems surfaced." So
they knew the problems before the Comet was built eh? The investigation
uncovered points that were unknown to science beforehand in metallurgy.





It was more than just a frame design, it was metallurgy too.


Yes, Boeing chose 75ST aluminum alloy for the primary structure. I don't
know what de Havilland chose, perhaps 24ST.



All of them means all types. Duh!


Well, if all airliners were similar to the Brabazon, the Brabazon couldn't
be ground-breaking in any area.
