Pilots and controllers are spitting coffee across the room
I realize movies get things wrong all the time, it's part of the game. Whether you're a doctor, bus driver, teacher or rocket surgeon when your profession is portayed in movies there will inevitably be times you shake your head and just say or think "no, no, no, no... that's so wrong".
Like I said it's part of the game and you have to take it with a grain of salt, it also makes you appreciate even more the movies that take the time and hire the advisors to nail it.
As a pilot when I watch a trailer for a movie based on an aviation incident and the only thing accurately portrayed is the coffee it's getting way too salty. I know this isn't a true story per say but you'd think they could spend 30 minutes talking to a pilot and a controller to at least get the basic communication right. The radio calls in this trailer are about the worst I've ever heard portrayed in a movie, it would be kind of like a surgeon looking at a nurse and saying "hey, put that sandwich down and give me that shiny sharp thing over there".
Terminology aside, if there was a pilot or controller on set and they heard one of the aircraft say they were going to descend (or climb, or turn) on their own because they "hadn't heard from the controller in a while" there would have been coffee flying out of mouths.
Like I said they're going to get things wrong but when it's obvious they didn't even try they've lost me.
But the father at the crash scene finding his daughter? That's just how the NTSB rolls, all hands on deck baby!
