So, we are aware this happened 3.6 hours after sunset? (7:54 pm local, sunset 4:14 pm local). Nightime.
It's not as thought the fugitive is going to be easy to track once he is into the grass islands and away from the ramp lights. (Remember a SWA 737 running into a ditch in darkness? 10 meters from the ramp edge?) Until he pops up in the aircraft lights.
And AFL2112 may have already been cleared for TO and lining up as the event developed. How long do we expect it to take for a ramp worker or guard to contact his boss, and for that boss to contact the tower, and for the tower to decide to cancel a clearance? Additionally allowing for startle-factor and situation awareness at each step - "what the heck exactly is going on here?"
