12 out of 12 - almost didn't make it - the first/last one the Super Beluga (had jet engines on it - if props it would have been a super guppie) was a correct WAG.
A toughie the Vietnam Air - just enough of the picture to betray what it is (hint the aft end of the engine).
To have an even chance to score at or near perfect one would need a lot of seniority (whiskers) to be exposed to all of these types.
Sadly missing a Vickers VC-10 the Caravalle the BAC 111 and the Convair series props and turbo props for tie breakers !

Now change the names to Military Nomenclature and the quiz will be off the charts !
