F-89 Scorpion - not one of Northrop's finer products...

Although, to be fair, may early jet aircraft had teething troubles.  Nevertheless, the F-89 never really came into its own as a first-line interceptor.  Underpowered, heavy, and supported by wings which had a nasty tendency to come apart under heavy loads, the Air Force limited the aircraft's speed to 425 mph-slower than many piston-engine fighters.

The aircraft in the photo is on display at the March Field Air Museum.
