In my AIRCAT files I found two typed pages of further information on this case.  Here are some more facts:

Source of Info:   Report abstracted from unclassified text from American Embassy (Dushanbe) (Escudero) by Jim Oberg.

Dated  January 31/0310Z

Photos:    Capt. Rhodes (allegedly) used his Olympus camera to get photos. He promised to send copies to Tajikistan desk (to Lowry Taylor) "if they come out."

UAP:  Very intense light appeared over the eastern horizon and approaching aircraft from E at "much higher altitude  than their own altitude."  Traveled at high speed. UAP maneuvered in circles, corkscrews, 90 deg turns, and high g-s.

UAP Shape:   Due to darkness its shape could not be determined.

UAP Atmospheric Effects: The "light" had a "bow wave" that looked like a high-speed photo of a bullet in flight.  The airplane flew under a contrail (allegedly) left by the UAP some 45 minutes later.  Capt. Rhodes estimated the altitude of the contrail at about 100,000 feet.

UAP Disappearance:  Assumed a horizontal flight path and accelerated out of sight over the horizon.

Comments:  This report does not state the aircraft's heading at the time of this event nor many other important flight details.

Jim Oberg supplied additional data on the launch from BAIKONUR COSMODROME (46 deg N;  63 deg E) in Kazakhstan of a Soviet Progress M-21.  This supply vehicle was launched toward the MIR space station at 0212 UTC on 28 January.
