Most articles I have read places the " Jetpack " 300 yards from the airliners.
Had I said " Improbable " as opposed to " Impossible " the thread would have progressed the same. The tone of this thread has more to do with the people involved then it does with the actual event.
That said, I am in good company with the word "Impossible" as the CEO of Jetpack Aviation uses the same word to describe pulling off this feat without the use of a parachute. It would be IMPROBABLE that a parachute coming down in densely populated South LA would go unnoticed.
