my question to u is do the creators of xmen have sum thing spcial to do with the us government beause in the films the x jet is a sr-71 in the games the x-jet is a b-2 and also in the game it mentions HAARP and lockheed several times

I would think not.

The planes are just that, planes. They liked the designs and used them.

HARRP and Lockheed are both well known, so its not that suprising to see them pop up in a film and game that is set in the modern world, with a few exceptions of course

But again, I don't think that there is a conspiracy between the people who made the X-Men movies and game.
