They apparently were not aware that Bro Tomahawk or Gigachad would be on the flight

8 more skeleton hijackers have been identified. On the night of December 11 they were mostly in different locations across the stream before arriving in San Pierro. Between 3 and 1 hours before the flight they all checked in for MSMG Airlines flight 69, and boarded. The 32 hijackers constituted one third of that day's load on the flight.
