Try to find the spot where the photographer was standing.
Looks like gun camera footage of a MiG 21. Probably from the '73 war.
The note seems to be from Avihu Ben-Nun (Hebrew: אביהו בן-נון), “the 11th commander of the Israeli Air Force between 1987 and 1992”.
I see some Google hits for "Avihu Ben-Nun Randy MiG" mentioning a Randy Ball, who could be the same one that this inscription refers to:
Randy W. Ball / MiG Pilot is a sixth generation Texan who spent his early years in rural Texas, the same as most of his ancestors, graduating from high school with a class of only 29.All of Randy’s time, however, wasn’t spent on the ‘ranch’. His father took him flying and he spent countless hours with one of his heroes, his Great Uncle Gilbert Ball, who flew 56 missions over Europe flying the B-17 Flying Fortress. Randy would ask questions and listen to his uncle’s stories by the hour. Even before college, Randy knew he wanted to fly. By the time he was 13 years old, he had already taken off and landed a plane with his father and soloed at the age of 18.To date, Randy has appeared on TV and Film, in dozens of magazines, and flown in front of millions of air show fans.Today Randy is recognized as one of the premier air show pilots flying jet aerobatics.
