The US president's counter-terrorism adviser John Brennan said the fatal UPS mail cargo flight crash over Dubai on September 2 is to be re-examined to find out if it was not caused by an explosive package collected from Yemen. He disclosed this in an interview to CNN Sunday, Oct. 31.DEBKAfile's counter-terror sources report that if this is what happened, US intelligence missed picking up on al Qaeda's air package plot for two months.
