We have a special page in our website dedicated to Jet Pack UFOs of which we currently have three videos. They are all quite interesting and we always assumed that the pilots were either extraterrestrial or human. Joseph Trevithick writing for The Warzone poses the idea that they may very well be unmanned and simply drones. That may explain a few things such as the elevation for the LAX sightings, but maybe not everything. This is an interesting article and includes federal aviation records of the incident and you can find it all HERE.
