Iron Man - Not High Enough
When Stark is first testing the Mark Ii armor he asks Jarvis what the altitude record is for the SR-71. Jarvis' response is that the "altitude record for fixed wing flight is 80,000 ft." This is wrong on 2 counts. First is that the altitude record for fixed wing flight is 123,000 ft, set by the MiG-25. But even if limited to the SR-71, Jarvis' answer is still wrong, sing the SR-71's altitude record for horizontal flight is 85,000 ft.
