Reply to comment by newtoon in Seattle-based Jetoptera is developing a vertical takeoff aircraft that can travel at almost 1,000 km/h with a radically simplified new type of engine. With almost no moving parts, it uses super-compressed air to create vortexes for thrust. by lughnasadh

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

The compressor though will certainly have some inertia won't it? Not quite auto-rotation levels of power but, maybe enough for the chute to deploy.

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