In the United States, the transition altitude is 18,000 ft. Flight levels, which are approximated altitudes based on standard air pressure, are only used above the transition altitude, as it simplifies operations at high altitude. However, under 18,000 ft, the actual altitude as read using the correct local air pressure is used instead, and expressed in feet, not flight levels. Therefore, an air controller would not ask an aircraft to descend to flight level 65, but rather ask to descend to 6500 ft. Correction: This statement is true for the United States, but not every country uses 18,000 ft as the transition altitude. Germany for example uses 5000 ft, and in Switzerland it's 7000 ft. So, issuing a clearance to FL 065 is correct depending on the country. This accident happened over Germany.
The local tower controller is seen handling aircraft well outside of the tower's airspace. Generally, the tower handles traffic within a 5-mile radius of the airport and altitudes of up to 4000 feet. While it makes for a better visual to have the background of lights and runways, in reality, the flights would have been handled in a dark, dimly lit room in the TRACON.
It is highly suspect that the controller in the movie kept removing his headset. Even if trying to place a phone call, he should have his headset on at all times. The fact that he took his headset off meant he missed the vital warnings from the pilots, and essentially allowed the collision to happen.
When the controller realized the imminent crash, he called out to one of the flights to ask if they could hear him. What he should have done, was called out an order to both flights. For example: "Flight 1, climb and maintain 1-zero-thousand turn left heading 360 expedite." Then the other one, Flight 2, descend and maintain 8-thousand turn right heading 180 expedite." Yet another instance where he allowed the accident to happen by giving the wrong orders at the wrong time.
Both aircraft could not be flying at 10,000 feet. FAA rules would require flight AX-112 to fly at odd altitudes, while flight DH-616 would fly at even altitudes, maintaining at least a 1,000 foot separation between aircraft to prevent exactly this kind of accident from occurring.
Younger Samuel eyes color were brown , turn to blue in older Samuel scene at the Cemetery. It is possible for someone's eye color to change as they get older.
A family member would not be allowed to the scene of a fatal air collision in which their loved ones died. Correction: The person reviewing the volunteers did routinely ask if they were family members and did check ID, yet Roman was able to slip through. This is probably consistent with the story, showing the consequences of a series of human mistakes.
When we're in the tower in the beginning, Jake is putting on his headset and contact Airbus EF-135. The rain/snow outside is being sprayed on the window from a nozzle underneath, you can see it's going upwards and arc back down closer to the window in the background.
At around 00:16:57 you can see the ATC-screen. Both planes are shown with an airspeed of 500,0 kts below 10 000 feet. This speed is much to high for this altitude for commercial airplanes.
It seems highly suspect that volunteers (instead of professionals) would be allowed to assist in searching through the wreckage of an airline disaster.
When Roman is viewing the Arrivals screen at the Columbus airport, one of the arrivals is from the same airport -- Columbus, Flight 3322 at 11:34 AM.
