Three words: Russian Quality Assurance
conversation overheard in Russian AF AC Maintenance hangar “hic...close enoughski Ivan hic...” clang...ooopski bringski precision hammer Ivan....hic that’ll buff right out no one will notice hic.....
THAT’s what I was thinking, exactly.
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...
That’s what sunk the Soviet sub K-219, a Yankee class. Drunken pipe fitters in the shipyard.
