Quiet day in the office...so here goes, old PI skills....
Take a close look at Google Earth, and you can, just about, make out reg's on the wings of the IL86 (RA86103)
and IL76 (RA76460). Put those reg's into a good photo website, such as Jetphotos.com' and there they are !
Put in one of the same photographers names in the JP filter, specify TU154 and Sheremetyevo and...eureka....RA85663 !
You're welcome...
