What prompted the backlash is how the airline and officers handled the situation -- both aboard United Flight 3411 and in its initial response Monday. Passenger: The man initially volunteered to leaveAfter passengers already boarded the plane, United said it needed to clear some seats because four members of another flight crew needed to sit down . The man who ended up bloodied and screaming Sunday night had initially agreed to get off the plane, passenger Jayse Anspach said. The harder the officers tried to get the man to leave, the harder the man insisted he stay.
