“While there is nothing at this time that leads the Department of Defense to believe this is a missile launch, the department and other U.S. government agencies with expertise in aviation and space continue to look into the condensation trail (CONTRAIL) seen and reported off the coast of southern California on Monday evening.

“All DoD entities with rocket and missile programs reported no launches, scheduled or inadvertent, during the time period in the area of the reported contrail. NORAD and USNORTHCOM confirmed that it did not monitor any foreign military missile launch off the California coast yesterday and has determined that there was no threat to the US homeland.

“In addition, the FAA ran radar replays from Monday afternoon of a large area west of Los Angeles. Those replays did not reveal any fast-moving, unidentified targets. The FAA also did not receive reports of any unusual sightings from pilots who were flying in the area Monday afternoon.
