Tripwire

Seeing the tripwire of a nearby bouncing Betty gave us cold chills, and we moved all the more slowly through the woods.

They watched the two ghost-hunters run own the corridor and go crashing over the trip-wire.

Thirteen people were injured in August 1957 when this Bristol freighter skidded on the runway at Southend Airport when landing with a flight from Calais. It ploughed through the boundary fence, but thankfully stopped short of the railway and the 1,500V overhead wires. A tripwire was installed on this section of Shenfield-Southend line to warn train drivers of instances such as this.

The continued presence of U.S. troops as a tripwire force in Macedonia is an increasingly risky venture.
