Factual error: During the decompression the plastic water bottles crush. The opposite should happen, as a decrease in external pressure would cause the bottles to expand.
Character mistake: During communication with ATC the co-pilot states their call sign followed by the read-back of ATC instructions. This order is incorrect. In reality a pilot or co-pilot reads back the instructions from ATC and then their call sign or tail number prior to ending their transmission.
Continuity mistake: When the plane is on the ground, it has two engines. When it takes off, it has four.
