A 22-year-old man who police suspected was drunk when he crashed through a fence at San Antonio International Airport Wednesday morning -- his birthday -- is facing multiple charges.

San Antonio police say William Ware has been charged with criminal mischief and trespassing, DWI and resisting arrest.

Police say Ware drove onto a restricted area of the airport just before 3 a.m. on Wednesday and nearly hit a parked aircraft.

The FAA halted air traffic and police had to chase his swerving car down the taxiway.

They were finally able to stop his vehicle as it crossed onto a runway.

Officers say Ware crawled into the passenger's seat and officers pulled him out of the car.

He was found with an illegal knife and an empty bottle of Bud Light on the floorboard.

As he was being handcuffed, police said Ware yelled out that he was a genius and that he was going to be "the best of the best."

He said he was a security guard and had to practice drunk driving on runways as part of his training to join the FBI's elite SWAT team.

He failed a field sobriety test and was arrested.

On the ride downtown, officers say Ware removed his seat belt and kicked the partition in the back of the squad car because he said it was his "duty" to try and escape as part of his secret FBI mission.

Then in the parking lot of the magistrate's office, he head-butted an officer.

Several officers had to help take him inside.
