PBS ran a series in honor of Einstein's 100th, and the US Navy did indeed take a matched pair of cesium clocks, and fly
one of them around for a while, and yes, the one in the air "slowed".

I didn't think of using the Earth's rotation at different heights to do the experiment. Pretty constant v for each clock...

Interesting, but still inconclusive it seems to me. If there are competeing effects, perhaps the one that slows it down at higher altitude wins. All the variables would not have been accounted for in that experiment, presuming it was conducted as you just said.

I'm not trying to be stubborn, just trying to understand it.
