Two brothers were arrested at Miami International Airport after one of them allegedly punched an American Airlines pilot. American Flight 1755 was headed to SFO but returned to the gate after Jonathan Baez, 27, had looked unresponsive and drunk. He was sleeping and not wearing his seatbelt.

The flight attendant attempted to wake him and noticed his condition, alerting the pilot to return to the terminal. As Baez was being taken off the plane, his brother Luis Baez, 29 decided to get regarded and fend for his brother.

As CBS reports, Jonathan at first left the plane without incident but Luis became aggressive and threatened the pilot, saying, "When you fly to San Juan, I will have you killed." Both brothers are from Las Piedras, Puerto Rico.

Few moments later, both men left the plane, Jonathan reportedly returned and punched the pilot in the face. A flight attendant who tried to break up the fight was hit in the shoulder. The brothers over again returned to the jet bridge to walk towards the terminal, with the pilot behind them. They then reportedly bounded him again and proceeded beating the pilot.

As ABC7 describes, as the final attack began, passengers jumped in to aid save the pilot.

They were then taken into custody and transported to the Miami-Dade County jail. They have been charged with provoked battery, motivated assault, and simple battery. The FBI is also involved in the probe because attacking an airline crew member is a federal crime.

A few hours later, the flight was able to take off with a new pilot. It reached SFO early this morning.
