A 22-year-old Ohio man was duct-taped to his seat after harassing and fighting with flight attendants during a Frontier Airlines flight from Philly to Miami. Authorities say the passenger, Maxwell Berry, groped two female flight attendants, then punched a male flight attendant in the face. He also emerged from the bathroom without a shirt after spilling a drink. Berry remained taped to his seat until police boarded the plane to arrest him. He's charged with three counts of battery.
