AD304 – Air Drops featuring metal cut from TT-1 BuNo 144227. The Temco TT-1 Pinto is an introductory and experimental jet trainer developed for the United States Navy. Powered by a Continental YJ69 T-9 turbojet engine, the Pinto had a top speed of 345 miles per hour and entered service in the late 1950s with Naval Air Training Command in Pensacola, Florida, to test the feasibility of using jet-powered trainers for primary flight training. Due to insufficient performance and limited endurance, the TT-1s were retired in the early 1960s. A single prototype (Model 51) and fourteen TT-1s were produced and the Navy sold the airframes as surplus.
 
T-37B - A Solo Air Drop cut from the a wing flap off of aircraft 58-1975 OR the fuselage off of aircraft 68-8019. This T-37B Air Drop will only be available in this combo or later in Stacks. The Cessna T-37 Tweet is a jet powered training aircraft first delivered to the United States Air Force in 1956. The T-37A was underpowered and a T-37B variant was developed that increased thrust by 10% and offered improved avionics. 552 T-37Bs were delivered to the USAF through the early 70s, and the entire T-37A fleet was upgraded to T-37Bs. The Air Force retired the aircraft in 2009. The airframe was also used to develop the A-37 Dragonfly – a light attack aircraft that saw combat during the Vietnam War.
