Thomas Nilsson has released his SAAB J35 Draken 3.2 final update for FS2004 on Bookmark Flightsim:
I just took the Draken up for a short 1st flight and I must say this is a real gem! The comprehensive online manual perfectly talks you through procedures like powering up the systems and starting the engine.
IMHO the Draken belongs in the same premier league as the Rollus Mirage 2000-F5 or Ivan Jurcaga's MiG21-F13. Unbelievable quality planes like this come as freeware!
