GTA V Easter Egg in Max Payne 3

I was just browsing GTAFORUMS and noticed a post by user CantPauseToast, Who made a pretty cool discovery while playing Max Payne 3 multiplayer. 


He found an office with images of planes up on the wall which look like they were recorded in-game.


However, the planes don't appear in Max Payne 3, and 2 of them look identical to the planes featured in last year's Grand Theft Auto V debut trailer. 

So there's a very good chance that the screenshots in the above picture were recorded in GTAV! Source
