Operating outside of runway classification. Prob only suitable for light prop aircraft.
I worked on the Typhoon fighter years ago, mechatronics for the control surfaces and munitions handling. Got to see some configuration testflight takeoffs at BAE Warton and on one occasion witnessed an aborted takeoff. That made quite a mess of the runway! Pilot ejected safely although i thought he was toast initially as i didnt see him eject, only the gentle decent of his parachute after following the fireball rolling down the runway.
Was nothing to do with me,i'm absolutely sure of it :?
