“Center, Aspen 20, you got a ground speed readout for us?”

In his book, “Sled Driver,” SR-71/Blackbird pilot Brian Shul writes:

I’ll always remember a certain radio exchange that occurred one day as Walt (my back-seater) and I were screaming across Southern
California 13 miles high. We were monitoring various radio transmissions from other aircraft as we entered Los Angeles airspace.
Though they didn’t really control us, they did monitor our movement across their scope. I heard a Cessna ask for a readout of its ground
speed.

“90 knots” Center replied.

Moments later,a Twin Beech required the same.

“120 knots,” Center answered.

We weren’t the only ones proud of our ground speed that day…as almost instantly an F-18 smugly transmitted, “Ah, Center, Dusty 52
requests ground speed readout.”

There was a slight pause, then the response, “525 knots on the ground, Dusty.”

Another silent pause. As I was thinking to myself how ripe a situation this was, I heard a familiar click of a radio transmission coming from my back-seater. It was at that precise moment I realized Walt and I had become a real crew, for we were both thinking in unison.

“Center, Aspen 20, you got a ground speed readout for us?”

There was a longer than normal pause … “Aspen, I show 1,742 knots.”

No further inquiries were heard on that frequency.
