Just as with many things it takes "two to tango". Training yourself to watch the area around your plane you can determine if someone is getting close. You then have a split second to make a manuever to avoid the collision. YOU are responsible for YOUR plane. As the pilot YOU can prevent ANY midair once you know how.

Making each other pay for each others plane is a very slippery slope. EACH person is 50% WRONG in every midair. IF EITHER pilot was aware and paying attention to the other traffic in the immediate area in front of their airplane they could have made a small course correction to avoid it. IF you fly ahead of your airplane instead of reponding to what is or is not doing you will not have a midair period.

When you are flying you must be AWARE of what is in your flight path or may cross it. Pay attention listen for engine noise the same volume as yours if you are flying into an area. Use your vision and don't "Tunnel vision" on your airplane. Become aware of the other traffic you can get an idea where other aircraft are at by using your vision and your ears. You will generally have at least one second to respond if another airplane comes into your field of view. You have to react and not freeze or panic. Hovering aircraft make a distinctive noise whether it is electric or powered. Learn that noise.

The jet versus foamie should have never happened the jet pilot should have made a "HIGH PASS" first to ensure the runway was open for a low pass. A foamie over the runway hovering was still making noise. If he had been aware of his surroundings and he could have made a correction if he was flying far enough ahead of his airplane.

The OP is doing the right thing by letting it go. In time he will learn who he can fly with and who to watch out for.
