An unmanned aerial vehicle (UAV) flying method for helping an UAV flying to a location of an owner of the UAV or flying to a predetermined place includes the following steps of: triggering the UAV into a hijacked mode; ascertaining if the UAV is capable of flying or not; the UAV flying to the location of the owner or to the predetermined place if the UAV is capable of flying; and, the UAV sending a distress signal to the owner if the UAV is not capable of flying. Therefore, the UAV is capable of flying back or sending information after entering the hijacked mode, so as to avoid or lower the loss caused by losing the UAV or the UAV being captured by the captor.

An unmanned vehicle is disclosed. The unmanned vehicle includes an aerial platform, a piloting system supported by the aerial platform, a medium source supported by the aerial platform, and a control system having a processor running computer executable code that actuates the medium source to emit a medium away from the aerial vehicle with an intensity sufficient to disorient a subject when the medium interacts with an exteroceptive sense of a subject.

An unmanned vehicle capable of operating in harsh environments is disclosed. The unmanned vehicle includes an aerial platform, a piloting system supported by the aerial platform, a medium source supported by the aerial platform, and a control system having a processor running computer executable code that actuates the medium source to emit a medium away from the aerial vehicle with an intensity sufficient to disorient a subject when the medium interacts with an exteroceptive sense of a subject.

The Aircraft Secondary Barrier Cart includes a main housing, with at least two retractable cables with metallic safety-hooks at the ends that connect to the two female loops behind each bulk-head. When deployed, the two cables hold the barrier cart in place. The two retractable cables are connected to a ratcheting system to stabilize and strengthen the barrier cart's stability after deployment. The ratcheting system includes a release lever to disengage the two main-housing cables before stowage. The barrier cart includes a folding-barrier with elastic and polymer safety-hooks sewn in. When the curtain or net gets expanded, its safety-hooks attach to several female loops riveted into the upper portion of the forward galley entrance.
