when you have loose power, with box wing design you can still glide, with their other designs you need a parachute.
Helicopters can auto rotate, but they can't pop up a parachute. Russians tried blowing the rotor blades of for a parachute, but it never got anywhere.
But in low speeds and low altitudes, this might be more dangerous than a helicopter

good point, but if you are below certain altitude chute wont help at all.
