At least, not in cases like this:
A stowaway crocodile on a flight escaped from its carrier bag and sparked an onboard stampede that caused the flight to crash, killing 19 passengers and crew.
The croc had been hidden in a passenger’s sports bag — allegedly with plans to sell it — but it tore loose and ran amok, sparking panic.
A stampede of terrified passengers caused the small aircraft to lose balance and tip over in mid-air during an internal flight in the Democratic Republic of Congo.
The unbalanced load caused the aircraft, on a routine flight from the capital, Kinshasa, to the regional airport at Bandundu, to go into a spin and crash into a house.
