US Military Security

Bryan Hopkins, a former marine, was able to board the aircraft carrier USS Constellation using an old ID card, and a uniform he found in a rubbish bin. And spent several weeks on board without being discovered. He didn’t bother hiding (in the way that, say, a illicit stowaway on a passenger liner might need to), he just ate, used the gym and bunked down with the regular crew.

The deception was only discovered after someone phoned the Navy office to tip them off.
