Boeing Skyfox

The Boeing Skyfox was designed to be a light and economical jet trainer as well as a light ground-attack platform. It competed against the Cessna T-37 Tweet and was intended to replace the Tweet in the future. The Skyfox was a heavily upgraded version of the wildly successful T-33 Shooting Star. In fact, purchasing a Skyfox meant you would get a T-33 with a conversion kit. It was designed to be built as a conversion kit on existing T-33s. The Skyfox's operational costs were half of the T-33's and comparable to the BAE Hawk and Alpha Jet. At the end of the day, there were no actual customers for the Skyfox, with the USAF choosing the T-37 instead. The T-37 was later converted to the successful A-37, so not all potential was lost.
In my opinion, it is an incredibly sleek and good-looking plane. Shame it wasn't developed further - It had some very redeeming qualities - It was good performing and cheap to operate. However, deals with both the USAF and Portugal Air Force didn't work out and Boeing didn't have enough buyers to justify continued development. Only 1 prototype exists.
