The question is certainly a paradigm of sorts.
I have personnally witnessed the insides of transmissions, one of which was removed from a helicopter of the, "so called Famed" blue Eagles, which had been removed at 28, - THAT IS TWENTY EIGHT TOTAL HOURS FROM NEW.
On the tag was the reason.
- INTENSIVE FLYING-
Now I have to say that some of us took the mickey out of this little predicament quite some,I mean we flew 'em - an flew 'em - an' held our mouth, jess right, (well we thought so) an' we used words like 'tally ho' and bandits (cattle) at your 4 oclock, an' we wore RAYBANS and dramk beer like it was goin' out of fashion, - an swaggered around and none of our transmissions still had the blue on the gears after all'o'that, an we thought we had been misled.
So for the aerobatis team, the Blue Angels, just what is "AEROBATIC FLIGHT"?
