On Wednesday, October 11, 1990, a small blue-and-white jet took to the air
from Air Force Plant 42 at Palmdale, CA. For the next 38 minutes, it cruised
at 10,000 feet over California’s Antelope Valley, reaching a top speed of 340
miles per hour (mph) before Rockwell International test pilot Norman K.
“Ken” Dyson returned it gently to Earth.
