I hope this hasn't already been mentioned...
I used to work with an army tech who was good mates with oz army pilots and he swears by this... A blackhawk was coming in to land from a routine training exercise full of grunts in the back. The pilots decided to have a bit of a laugh and over ics informed them that they were too heavy and low on engine power (grunts not knowing any better).
There is a pump in the cabin to charge the apu accumulator in the event the backup hyd pump fails to get it up to pressure, so the pilots instructed the soldiers to get to work pumping as hard as they could or they'd come in too hot and crash...
As about 12 grunts cycled through pumping the handle and screaming and just generally being all war-ie they flared and touched down and appparently it these lads in the back were jumping around like they'd won the world cup. Pilots thanked them for their efforts and walked away snickering...
