The F-111 oddly named the Aardvark is often called the Pig by crews I think.
On that theme I think the EF-111 Raven was nicknamed the Spark Vark.
The SR-71 Blackbird was called the Habu (type of snake common or native in the region where they were usually based) by crews.
Lagg-3 was usually called something in Russian corresponding to it's designation roughly translated as varnished flying coffin.
Another for the Lagg 3 and/or possibly the later La 5s (or maybe even an unrelated aircraft) was nicknamed 'the flying grand piano' or something like that, another reference to the wood based construction.
Il-2 Sturmovik had a few including Iron dog and Gorbatyi (meaning Hunchback)
German WW2 fighters usually got named with the designation, Fw190A = Anton, Fw190D = Dora, 109E = Emil, 109F = Frederick, 109G = Gustav etc
I think this is after the german phoenetic alphabet?
DC-3/C-47 Skytrain = Gooney Bird, Vomit comet
That Blomn and Voss flying boat was nicknamed the Flying Clog (looked like a shoe)
AD1 Skyraider = Able Dog
A3D Skywarrior = All Three Dead
Most very large aircraft like B-36 or C-5 = Aluminium Overcast
Many large transport aircraft like C-130 or C-5 are sometimes called Fat Albert
Many stripped out and lightened fighters in WW2 like the L model of the P-40 were called Gypsy Rose Lee after a famous stripper of the time.
