Drunken banter in a mess bar some 4000 miles south of the equator as to which aircraft had the best rate of climb.
The toom boys said it was theirs. "Rubbish" said the wokkas. Honour was at stake, so a comparison was to be made of the best brakes off to ten thousand performance.
A wokka mate sat in the back of a Toom and timed the climb. "Very impressive" said he. A toom chap sat in the Chinook and watched the crew get airborne, climb to 9900', release the parking brake and climb a hundred feet in a matter of seconds!
