What would an extended runway have anything to do with a company stating their rotorcraft are "runway independent aircraft". They would only need a short paved section of not more than a small flat pad for takeoff/landing. Gyros are draggy devices, they don't go fast and even the Carter copter was a failure enough even the military did not adopt them. I have been flying gyrocopters for years, they have been around awhile but why, even with todays technology they still cant seem to figure out the blade tip speed problems unavoidable at higher speeds.
