Duggan is accused by the U.S. of training Chinese military pilots in landing on aircraft carriers in coordination with a South African flight school, which authorities said dated back to the early 2010s, according to an indictment dated from 2017 and unsealed two years ago.

Australia's Attorney-General Mark Dreyfus said on Monday he had approved a United States extradition request for former U.S. Marines pilot Daniel Duggan, who faces charges including breaking U.S. arms control law by training Chinese military pilots to land on aircraft carriers.
