I think their T-38 inventory went up by one, they took a Sheppard T-38A that had a massive birdstrike and IFE'd into WWYK. Took out the pilots forward instrutment panel and a alot of sheet metal damage fwd of the windshield.This bird sat here for about 5 Months before the USAF
wrote it off and NASA took it back to Ellington stripping it down and loading it on a C-97 super guppy. It should be at El Paso finishing up repairs and modification.
The differences between the NASA and USAF
T-38's are Martin Baker ejection seats, different avionics, weather radar and automatic crossover valve for bleed air at engine start. Most of the NASA fleet has the chopped engine intake and exhaust flapper doors like the the Moody USAF
T-38C jets for better takeoff performance on hot days.
