They are also significantly more dangerous than an airplane though. The skill and speed needed to cope with an engine failure is a lot less forgiving and helicopters nearly always spend more time at lower altitude. Also the number of mechanical failures that result in everybody aboard essentially guaranteed dying is higher in a helicopter. Especially vs a small airplane with a parachute (parachute systems on helicopters are extremely rare especially due to altitude requirements)
