The BBC reports:

Heathrow Airport’s controversial Terminal 5 is set to be opened by the Queen in a ceremony involving hundreds of airport and construction workers…

…The opening follows a major security alert at the airport on Thursday after a man with a rucksack scaled the perimeter fence and ran into the path of an aircraft.

It may be worth noting that he was nowhere near Terminal 5.

The man was arrested and a controlled explosion carried out on his rucksack. Police said the incident was not terrorism-related

Not terrorism-related? Huh. So police routinely carry out a controlled explosion on your average criminal’s possessions?
