Type MDH 902 Explorer, c/n 900-00074, based at RAF Waddington. Of special note is the unique NOTAR Anti-Torque system. There is no conventional tail rotor but air is blown through a long slot along the tail boom to stabilise the aircraft. With the NOTAR system a sliding circular cover near the end of the tail boom is opened and closed to adjust thrust.
