For example the 747SP would be nice, given it was in production in 1982 and poses some interesting tradeoffs while making transpacific service possible (in fact Pan Am did the first nonstop SYD-LAX flight in 1982 in an SP!).
The Tu-144 was also in “production” though fairly sure I’ve not seen Concorde or Concorski operation anywhere in the game previously.
Aware it’s not high priority but given that wright is heavily flavour oriented it would be nice to have a slightly more diverse roster than the Maddog/757/747-200B combos that seem to be proliferating everywhere
