Someone at a CPA interview...
If you opened the cowl (as we do all the time) what difference would you find between a Rolls Royce powered 744 and a GE powered one. Piss poor interview technique but the interviewer was angling for an answer along the lines of triple spool vs twin spool.
The actual answer given, "One says, 'Made In England', and the other says 'Made in the USA'?
Sadly he wasn't employed, but priceless answer.
