Actually, during the second world war, the soviets brought
an famous aviation designer out of the gulag to figure
out why their planes were crashing.
He watched a crew assemble one and found that the cause
was miss alignment of the wing and spar and the crews
were driving the bolts home with a sledge hammer, stressing
the spar and causing it to fail...
Musta been a Jew. Did they send him back to the Gulag?
