The Gross Sky Ghost is an American high-wing, strut-braced, two-seat, glider that was designed by Frank R.
[1][2] Gross was a graduate of Akaflieg Darmstadt and the Sky Ghost was his third glider design after the Baker-McMillan Cadet and the Akron Condor.
In the 1930s most glider flight training was accomplished by having a student fly short hops under supervision of an instructor on the ground.
The landing gear is a conventional arrangement for fixed wing powered aircraft, rather than the more common central monowheel used on gliders.
[2] The first multi-place glider flight of over two hours ever flown in the USA was completed by Gross in the Sky Ghost.
