Michael Haak was piloting a Southwest Airlines plane when he allegedly engaged in lewd behavior mid-flight, police say. Haak left the airline before it became aware of the situation, the company says in a statement. He is accused of exposing his genitals during the flight, which took off from Philly headed to Orlando on Aug. 10; per the court filing, he "intentionally committed an act of lewd, indecent and obscene exposure of his genitals in a public place." Not many more details have been made public, including where the alleged act took place, NBC Philadelphia reports. But ABC News reports no passengers are said to have witnessed it, only the pilots.
