It is a tiltrotor yes, but part of the requirements are for a conventional take off and landing.
Our outline plan for actions after the pilot has turned a funny colour is to have the thing broadcast a distress message, plot a course to the closest suitable airfield and head there asap.
The problems are overcoming the communication issue. It's easy enough to transmit a pre-recorded message, but we're not sure speech recognition is sufficiently mature to interpret instructions from air traffic about clearance, runway etc.
We don't want to rely on a ground controller to fly it like a UAV, as this would be costly to support for any purchaser. Plus the opportunity for terrorist takeover of course...
