Let me ask a question of those who see the sim as completely innocent.
Suppose a plane disappeared under odd circumstances such as this one did. After the disappearance, it was found that the pilot had a very elaborate and expensive sim setup hidden in his basement which nobody knew about.
Then would you find it at least a little suspicious?
DID you really seen his cockpit pictures?
Few toys from Saitek, computer, few LCD, nothing more. Nothing really expensive. And nothing hidden - as he posted pictures on web by himself.
Just another childish conspiracy theory based on REALLY twisted facts.
