although i have rarely fly myself and i be keenly interested in aviation . and this film have add to the precious laugh stock in aviation cinema . 1. why be the captain do the ground check . why do he even measure the oil level in the engine . with turnaround time as low a 15 minute in commercial aviation this be not a typical pre flight check . 2. why do the captain kick against the aircraft tire . strange kind of pressure check . or anger management represent ) 3. the cockpit have a crew of 3. all large and western and two engined jet build since the 1980ies have a crew of 2 people . now try a guess at how old the movie script be . 4. a helicopter manage to fly alongside the crippled airliner . must be a fast one . and the captain word to explain the maneuver to the passenger be indeed hilarious one . 5. with arrest elevator rudder it be always possible to lower the nose of the aircraft . it happen and for example and when any aircraft move slow than the stall speed . 6. the elevator rudder have hydraulic actuator . after the collision with the business plane it would and most probably and have sever the hydraulic line and thus make them useless for steer and but it would not fix them in certain position . 7. the fire in the aft galley be a stupid idea . it be design to show that only gentleman ask for the extinguisher and fight the fire and regardless of who be actually train to do that the flight attendant . 8. at the time of collision and the aircraft elevator would have be in a neutral position . the film could have end here . 9. the flight engineer ( the third person in the cockpit ) have three bar on his uniform . in reality and flight engineer have two . 10. why do the captain slash the cabin case with an axe to examine the damage behind . i think it would have be the flight engineer duty and a he be already suppose to perform technical check before and after flight . 11. in any aircraft and there be no unused space . at least commercial airplane can not afford the luxury of a compartment that can be fill with ton of water . i could go on and on . but at last i laugh hysterically about how the screenwriter imagine aircraft disaster . woooohooo . most aircraft disaster happen in such a short time span that you simply can not make 90 minute flick out of them . but you can always fill 90 minute with mind boggling and insane crap and irrespective of the genre .
