Chuck Yeager also tells that story the two of them went off by themselves on their last mission together. saw nothing and dropped their tanks spent all their ammo tryin to make them catchfire.
meanwhile there had been a giant furball not far away and they missed tha action. when they got home their ground crew seeing the scorched wings from all the gunfire excitedly asked them how many the two of them had scored......
they had to sheepishly admit,that they had missed all the action...not exact words but as good as I can recall from the last time I read the story.
damage to the drop tanks would be cool but a fire???? highly unlikely....and please dont refer to the poor soul in the corsair that lost both tanks on landing and was burned to death
