This is an old VHS release entitled "Vietnam: Phantoms Of The Sky" that traces the history of the McDonnell Douglas F-4 Phantom II fighter jet during the Vietnam War. That war plane is probably the most famous fighter plane of that war.
The F-4 Phantom's role in lifting the seige of Khe Sanh is one of the key focuses of this tape. The box cover reads, "In air-to-air dogfights, F-4 Phantom Interceptors enjoyed a 5 to 1 kill ratio over the North Vietnamese MiG fighters which filled the skies over Hanoi. And during close-air support missions along the perimeter of the Khe Sanh Marine Base, F-4 Phantoms strafed, fired rockets and dropped napalm on advancing Viet Cong and NVA Positions until B-52 Arc Light bombers arrived to help lift the 66 Days Siege."
