How is this realistic? 'Terminate emergency or GTFO' 'But... MY ENGINES ARE ON FIRE!' Didn't know ATC had the power to "terminate" emergencies. Also, it would be pretty boring if all the flights went well... I mean, put some action in there. Flight sims can simulate emergencies, so why not. Hijacks would be pretty dumb to simulate though... but what if you lost control of your plane and it still hits a building? and... transponder code of 7500? Does that mean "I'M IN TROUBLE I GOT A KNIFE ON MY THROAT" ? If so... don't you think hijackers would know about this and do something when the pilot calls 7500? Like cut his throat, or whatever a terrorist would do to a guy not obeying his orders
