> Unlike a traditional airplane, it becomes impossible to command the airplane into a stall, a spin, unsafe attitudes, or other bad states.

Interesting product and definitely different from most YC startups we see!

However, I am curious how the above will be impossible. Since it is fly-by-wire it seems like there is always a chance your sensor/servo fails and causes bad input. Or a software defect causes bad input with no manual overrides to just fly the airplane.
