Top 3
Given that I fly on an almost weekly basis it's hard to add any variety to a staple diet of A32X, DH4 or Emb195 in my case but;
Top three (gone forever, in practial terms) VC10, 707, DC8
Top three (still in service) MD11, A340, B777 (yes I know easy to do if I spend some money)
Top three in my logbook Concorde, Comet, DC3 (with an honourable mention to the Shorts 330)
Cheers
