I would be very surprised if the FAA and Canadian, western European civil aviation regulators don't require something functionally equivalent to being able to operate with 25% of the lift rotors dead or disabled (an even higher degree of redundancy than a four armed, coaxial eight motor/prop octocopter filming platform today, which can lose 1 out of 8 motors and likely land safely), plus also a ballistic parachute. Something like what is mounted in the top side of a Cirrus VisionJet.
