While Joe flew directly above the tanks in around 5 kilometers height, Mad-E's spontanious actions distracted him from keeping the detabilized Swarm under control, and thus, the Swarm prompty tilted downwards and started spinning on a vertical axis. It quickly spun too fast for any human to hope to counteract it effectively. To save himself Joe attempted to get the NC's computer to 'lock' the controls' axes, so Joe wouldn't have to factor in the rotation himself when controlling, although that mode would make turning difficult, as the controls would always point north, even if the NC wasn't, which could lead to accidental sideways-walks. In his haste he accidentally dumb-launched a full volley of missiles, which quickly spread out in a circular pattern around the battlefield due to the centrifugal force. The Swarm however fell faster than its missiles, as it was still on full thrust, powering downwards onto the enemy, in what likely looked like a kamikaze attempt.
Joe was done with the 'locking' of his controls just in time, as it turned out. He pulled up immedeatly, the NC slowly followed his orders, degree by degree. Joe didn't remember whether or not he screamed while falling.
He would reach a horizontal course at about 1 meter above the ground, which luckily was rather flat. He was at a 45° angle, as the computer had almost fully stopped the rotation, and Joe noticed that he fired a volley of the missiles as one passed him within 100 meters. It was at that moment that he noticed, he accidentally surrounded the enemy on his very own. If he was to engage the aim at the right moment, the missiles would by flying at the tanks from all directions, impossible to dodge all, impossible to shoot down more than a few, the hits were almost assured. He waited a few seconds until the right time, then activated the aim-laser pointed at the tank that looked like it was in the best shape of all of the tanks.
As the Swarm had slowed down while turning, it was turning at a much faster rate now, but Joe would still get close to the ground. Unfortunatly, his discovery had distracted him from looking at where he was flying, so unlucky as he was, he ended up on a collision course with a lonely tree. The tree obviously didn't survive the impact, it was shattered while also being ripped out of the ground. It still did much damage to the NC, for a tree that is, and as a result the Swarm was unable to take off again in its current state without repairs, so it crashed. After rolling over while sliding across the ground, the Swarm came to a halt on its back, feet pointing away from the enemy, the rocket-launcher, while loaded and able to fire, was unable to reload automatically now; the aiming-laser still functioned. Joe was lucky to have put his seat-belt on, otherwise he would be either mush or jelly by now, and his neurological impant wasn't ripped out by the force, which would have pulled on the cable, if the plug had gotten stuck in the socket, and if he would have been flung out of his seat. The crash had pushed most of Joe's blood into his legs, so he fell unconscious for a short time.
When he woke up, he looked up, where the enemy was last seen by him from his current perspective, to see if the fight was still going. He had only one volley of missiles left.
