[time-nuts] historical photos and info about Hafele-Keating

[Noneayour Bsnes]

I teach physics, and I love the Hafele-Keating experiment as a way
to introduce relativity. Because the experiment has a lot of charisma, 
it's cool to be able to show students photos of the men and the
clocks aboard the plane. The general relativity text by Hartle had
a photo that he claimed was of Hafele and Keating boarding a plane,
but it turns out that that was a mistake. Some actual photos from
the experiment have been available online for a while, but they were
low resolution. I've obtained and scanned copies of these at higher
resolution and posted them here:

The copyright status of these photos varies, and in some cases is 
difficult to determine. I've given what information I had on the
web page. I'm in the U.S., where we have a pretty good fair use 
exception to copyright, and for the photos that are copyrighted,
I think I have an excellent fair-use claim.

I would be grateful to anyone who could e-mail me with any of the
following:

-any biographical information about Hafele or Keating, and contact
 information if they are still living

-related historical photos that are in the public domain and of high
 educational or historical interest

-information about the copyright of the photo that appeared in
 Popular Mechanics

Is anyone on this list old enough to have been involved in
relativistic atomic clock experiments from that era?
