I'm not surprised at all.....at one of the crew hotels near the airport there is a high security fence about 10ft away from a dedicated running track beside said hotel to stop guests being held up by the natives.
One would think that with the local police looking after the airport that security would be tighter but evidently not....
Having said that an airfield boundary at night is very easy to get through....so my advice for the airlines is a have a BIG chat with your corporate security guys/gals and see what the hell they are being paid for.
If unknown persons can pinch stuff from an aircraft there's nothing to stop them placing a barometric device onboard the plane and y'all know what would happen then.....
The local FAA dept should do regular ground checks and make sure that the airport is not a "soft" target for those groups wanting to make a name for themselves.
A sad day for aviation......
