One assumes this guy is the full quid when it comes to intelligence or he wouldn't be a BAE engineer. So presumably he either has some psychological problem or he wants to spend time at her Majesty's pleasure - perhaps he's trying to escape his spouse on a long-term basis.
What other reason could there possibly be for him doing what he did? He couldn't have been caught more easily other than to have walked out the gate and said to security "look what I'm carrying out".
