PITTSBURGH--An irate and belligerent Georgia man who told a flight attendant that he needed to get off a commercial airline that was in flight is facing up to 20 years in prison.

Marc Anthony Malone, 34,  pleaded guilty in federal court today to one count of interfering with a flight crew.

On Oct. 10, Malone board a AirTran flight from Atlanta to Pittsburgh. , Pennsylvania. About 30 minutes into the flight, Malone began acting erratically.

According to federal authorities, this is what happened: At one point during the flight, Malone asked a flight crew member, "Where are we?" Upon hearing that the plane was on its way to Pittsburgh, Malone stated, "I need to get off now," and attempted to get to the front of the aircraft. One of the flight attendants tried to calm Malone and asked him to sit in his seat, at which point Malone continued to leave his seat, stating, "Why are you mad at me?" Shortly thereafter, Malone attempted to force his way to the front of the plane, at which point two flight attendants physically stopped him, and Malone yelled "F-- you!" over and over.

As Malone refused to comply with commands to return to his seat, he attempted to get to the front of the plane by pushing a flight attendant with his hands, knocking the attendant backward, federal officials stated.

At that time two, flight attendants and five passengers wrestled Malone to the ground to restrain him and place flex cuffs on him, federal officials allege.

While Malone kicked and attempted to bite those that attempted to restrain him, Malone yelled, "I'm going to get you. When I get out of here, I can't wait to get a hold of you." As such, Malone had to be restrained by flight crew members for the duration of the plane's landing instead of being able to attend to their normal duties.

Malone will be sentenced in May.
