Some CIB agents said the in-flight escort mission was reminiscent of the Hollywood action-thriller film "Con Air, " in which a newly released ex-con and former U.S. Ranger found himself trapped on a prisoner transport plane when the passengers seized control.
Police sources said the CIB would send another chartered plane to Indonesia in the next couple of days to fly back the 100 suspects arrested there in the June 9 operation.
