If a helicopter's engines fails in mid flight, does the helicopter just fall straight down like a rock?

If one of the helicopter's engines stops running, the helicopter will still have forward velocity. In this case, the helicopter will start turning toward the direction where it's moving, which is likely a dangerous result, due to the helicopters' proximity to the ground. But if the helicopter was only a few meters above the ground, it might not make that big of a difference.

Do the spinning rotors still have lift without the engine?
user
Yes, the blades will still be rotating, even if they're not generating lift. So in this case, the helicopter will simply fall straight down, without any horizontal thrust.

It sounds like helicopters need very reliable motors.
