The video captured at Air Force in Ha Noi city, Viet Nam on May 07

There are many old fighter aircraft of the air force in the Vietnam War including: MiG-17, MiG-19, MiG-21, transport helicopters, underground hunting helicopters… including the A-37 aircraft, associated with many outstanding victories in two wars against French colonialism and American.

Other Soviet fixed wing aircraft include a Russian AN-2 Colt which is said to have been used in a rocket attack against a South Vietnamese radar installation, and a couple of training aircraft including a Czechoslovakian L-29 Delfin jet.

There are five intact American planes on display, an O-1 Birddog observation plane, an A-37 Dragonfly ground attack jet, an F-5 fighter bomber, an A-1 Skyraider and this UH-1 Huey. They're all in Vietnamese Air Force colors.

The bizarre looking Kamov Ka-25 "Hormone" maritime helicopter with twin contra-rotating rotors and no tail rotor, an Mi-24A "Hind" in its assault configuration rather than the much more familiar gunship configuration, an Mi-4 "Hound" piston engined light transport and my personal favorite, the massive Mi-6 "Hook" which can lift twice as much as the largest American helicopter, the S-64 Tahre "Skycrane", and can even carry 120 people in its high-density seating configuration.

All air aircraft are left outdoors, Standing outside in the tropical heat and in Hanoi's smog hasn't helped preserve them but they're in pretty good condition. Aircraft are preserved by the Vietnam Air Force.
