For today I think it would probably be the following, but then tomorrow it could be a totally different three
Avro York
Breguet Deux Ponts
Shorts Sandringham
or for jets
Dassault Mercure
Il 62
VFW614
Without going into sub types such as BAC 1-11 srs 200, 300, 400 etc but just keeping it is as BAC 1-11, I have clocked up 68 different a/c types flown in as a passenger which provide many happy memories.
