Factual error: During the emergency, Whip instructs Ken to dump fuel, and fuel is seen spraying out of the nozzle on the wing. MD-80 family aircraft are not equipped with fuel dump capabilities.
Suggested correction: The aircraft is a fictional Jackson Ridgefield JR-88 according to a slide shown during the NTSB hearing scene. This can also explain why it has winglets, another feature McDonnell Douglas MD-80 series aircraft do not have.
Continuity mistake: When Harling picks Whip up from the hospital, he says he couldn't find any suitcases at Whip's place, so he puts his clothes and stuff in garbage bags, but when Whip arrives at the farm, there are no garbage bags in sight, just a small suitcase and a small plastic bag.
Suggested correction: The suitcase is probably in Whip's car - no reason why he couldn't have shoved everything in there.
