Thanks... I am familiar with the work that user has done. This is a little different, though - we're using dongles instead of scanners, and up to 8 channels/feeds per dongle. So no sound adapters, no scanners, and a lot of other features.
I think I read somewhere that small, single engine planes are really susceptible to being tossed around by wind gusts...if there was a student pilot and he was caught off guard by one, and lost control of the plane...well one could have slammed into the other as a result.
Is there any more after this, reaction from the controller or anything? How this occurred is somewhat baffling to me -- it sounds like at least one had the traffic in sight visually, if not both of them seeing each other, and the controller sure seemed like he was really on top of helping them maintain separation. Sad.
