>You cant dead stick a cessna in an urban environment, and current ballistic parachutes aren't that heavy.

Except a ballistic parachute does absolutely nothing for you in the scenario where > 90% of accidents happen: take off and landing. Even the most advanced BRS systems on Cirrus planes require 1000 feet AGL. There's simply no getting around the basic physics of this problem.

Yeah but dead sticking is less effective during take off and landing as well.

I watched someone who wouldn't make the runway (pilot error, didn't switch the fuel tanks fully on approach) dead stick onto a perpendicular highway.

With a light plane, you can do a lot with a dead stick. They have remarkably generous glide slopes (nearish to a mile horizontal travel for every 1,000 vertical feet). Not to mention being inherently stable whether under power or not.

Well a 0/0 safety system seems like a solvable problem in the scheme of things. airbag + chute? Who knows.

You can't dead stick most aircraft in an urban environment. Unless you are Sully...
