Call sign SPADESMA. Up from Holloman AFB to Hill AFB for a couple hours. Now up again. Top speed looks to be around 600 knots. ICAO hexidecimal code AE6B64 returns no results.

Anon is going to crunch the numbers for timestamps vs. distance and see if can work up a reliable average speed. He has his speed display turned off right now. But it sure looks like he moved out of Utah in hurry. Once he is back on the ground at Holloman AFB will calculate round trip average speed minus time on the ground at Hill AFB.
