The JSF crowd here make it sound as if this Virtual training module which is used in the F35 is a groundbreaking new technology unique to the F35.
Maybe they should first figure out why it was exactly the Dutch (Fokker/NLR) who got the contract to implement this feature.
It is a very useful thing to have, something most airforces using HMDS-type systems will be able to use in the next decade.
One of the first is going to be the new NG Gripen and Rafale (and any other EADS related product BTW).
