The man, later identified as 58-year-old Marc Rehmar, actually stopped the driver towing the United Airlines plane from the gate and begged to be let on board. Within seconds, Rahmer was detained by the ground crew.
On Wednesday, Rehmar pleaded guilty to tampering was sentenced to probation and community service.
After watching the footage from the August incident, airline security expert Gregory Feith couldn't believe it.
He told INSIDE EDITION: "We all laugh at the fact that he is running after a plane like he is chasing a cab. The fact is, he presented a significant danger. The mentality of some of these folks just amazes me with some of their actions."
According to court documents obtained by INSIDE EDITION, "after arriving late for his flight [Rehmar] forcibly pushed open an alarmed door... Chased down a tug driver and insisted on boarding the aircraft."
