It had happened no more than once AFAIK

  while that may be true, you know that all ATC meetings had this reported to them so they are all aware and on the look out for it. it only goes to make sense. if someone was developing a jetpack unit, they would need to do multiple test flights. if they were dumb enough to do it the first time, they are probably willing to do it a second time.
