Nuggets and newbies and dweebs and...
Sorry if I offended any of the real pilots here.
Wolf has it right, and USAF called the newbies "Joe Baggodonuts", heh heh. The term "dweebs" had not been invented yet.
I adopted the term "nugget" due to my connections with Nasal Radiators way back then. It is used for the junior pilot or nav until he's in the other seat. No big deal, and the PF on AF447 was the most junior troop. 'nuf said.
All of we pilots were nuggets or less flattering descriptions in the beginning. We learned and we matured and we did just fine or wound up a smoking hole. Some great mentors led us, and we had the benefit of them along the way. Wouldn't be here today if not for them.
