A few more Aussie ones:
Bloke of surname Ward nicknamed Warthog, so when a younger Ward turns up at the same squadron he gets Piglet.
Spew (prone to airsickness in his early flying days),
Loadmaster called Phantom because he was hardly ever at work,
'Discrepancy', now a rather well known A380 captain whose surname sounds not unlike the nickname,
'Slops' Hislop, another loady
bloke named Stu, nickname 'Pid'
too many to list
