You stood in a darkened room and trained to get 'lock on' on the jet appearing on the big screen TV, then you'd fire. It was like playing a video game.
This launcher taken from whoever's trash has the flashlight gizmo in the tube and the training module dealie mounted on it. It only bears similarity to a real FIM-43 launcher.
I thought it might be a training device. Something about it didn’t look right. Pretty old school stuff alright. Redeye had a hard time hitting the fast movers, didn’t it?
