They chartered a large plane, but in the end, they didn't use it; Gao Guang and his team were eventually brought back on a military aircraft.
As long as Gao Guang returned to Los Angeles, his whereabouts would no longer be a secret, and then Morris could rest easy, and so could Lloyd.
Everyone believed that Gao Guang wouldn't dare to kill Morris on U.S. soil, which is why Lloyd stepped in, using a military plane to bring Gao Guang and his team to Edwards Air Force Base.
Officially, it was for convenience at customs, but seeing Gao Guang back in Los Angeles with their own eyes could put certain people at ease—that was an unspoken understanding.
Thankfully, although it was still a military transport plane, it had been fitted with seats, and since King's Defense was full of wounded, the noise might have been louder than that of a commercial airliner, but in terms of convenience, the military aircraft definitely had the airliner beat by a long shot.
