Re: Active shooters on runway at Vegas shooting.
I seem to recall there was an audio transmission of ATC telling a pilot that was landing to turn off the runway at a specific point because there was an active shooter farther down the runway.
Prior to that there was some confusion as to whether was a separate gunfight happening on the runway or whether someone was shooting at fuel tanks near the runway to perhaps cause an explosion/diversion.
I don't recall there being actual video of that situation but there was an audio recording of ATC talking to a pilot about it.
