This I can replicate! I was unable to reproduce this, until you provided a vital clue in the current message: "as they are about to trample all over you". I usually try to get off the runway ASAP using the UFO, when inspecting traffic behavior, so I missed this one completely. Initially, I was a little confused about the "teleporting" part of your bug report, but it makes sense now. You couldn't know, but the disappearing and "respawning" are two independent phenomena. There is some basic proximity detection code which cause AI aircraft to wait for the user's aircraft. More recently I added a new function that detects situations in the ground network were aircraft are eventually waiting for themselves. (i.e. a waits for b; b waits for c; but c waits for a). The occurrence of these is not frequent, but when it happens, the waiting aircraft can block all other traffic. Eventually, this needs to be resolved more gracefully, probably by moving one of the offending aircraft back, or by implementing more sophisticated "hold position" instructions. Until that time the offending aircraft are removed from the scene. It seems this function is triggered whenever an AI aircraft is waiting for the user. I believe a solution is fairly straightforward, but requires some more testing. I'll probably have something at the end of the day. The "respawning" on the other hand, is a different phenomenon. During initialization, the traffic manager makes an estimate as to which stage of a flight an aircraft is: Wait at gate / push back / taxi / take off / climb / cruise. When an aircraft is considered to be in the take off stage, it is placed on the runway, and given take off speed during initialization, thus creating the illusion of a spontaneous spawning of these aircraft. It's not really an ideal situation, waiting for refinement. FWIW, I also hope to have a look at the tanker speeds this weekend.
