Wondering what happened to all fuel tanks jettisoned by U.S. fighter jets over Southeast Asia during Vietnam War?

External tanks are extremely important for military aircraft as they provide fuel to integrate internal tanks and extend fighters and bombers endurance.

Indeed, even if they can be refueled by aerial tankers, tactical jet planes heavily rely on the JP-8 fuel loaded on the external fuel tanks. However, the auxiliary fuel tanks represent an additional weight, additional drag, and they will reduce the aircraft maneuverability.

In real combat, external fuel tanks are jettisoned when empty or as soon as the aircraft needs to get rid of them to accelerate and maneuver against an enemy fighter plane or to evade a surface to air missile.

Several thousand drop tanks were jettisoned over Southeast Asia during the Vietnam War.

And here you can see what happened to some of those that were recovered.
