The mystery of the menacing-appearing contrail that appeared 35 miles off Los Angeles on the evening of November 8 appears to have been solved: US Airways Flight 808 was approaching the Los Angeles area at the time, on its way from Honolulu to Phoenix. The plane would have been flying with a filed flight plan because it was in Grade-A airspace and flying under instrument flight rules. Despite that the flight plan would have been readily available, neither the FAA nor the Pentagon appeared able to identify the craft, and it took civilians to research flight schedules in order to make the determination of what it probably was. And yet the Pentagon announce immediately that it post no threat to US airspace, even before they apparently had any idea what it was. And they still appeared mystified 24 hours later, saying only that it "appeared" to be the contrail of a jet.
