Forgotten Canadian Weapons Block UK Runway

Danger room has a blog post about a World War II Canadian weapon that has blocked a runway in the UK. The Canadian Pipe Mine (also called a 'McNaughton Tube') was a device planted under airfields so that the runway could be destroyed if attacked. This would have been very useful in WWII when gliders were used by airborne troops to carry heavy equipment and supplies.

In the case of Daedalus Airfield in Hampshire, the weapon was forgotten about and never removed after the war. It was discovered last year and had to be carefully removed by the Royal Engineers.
