Bird/Wildlife Aircraft Strike Hazard cannon
A new Bird/Wildlife Aircraft Strike Hazard cannon aims towards the sky after being installed at Yokota Air Base, Japan, April 11, 2014. The remote-activated, solar-powered cannon simulates threatening sounds, such as predator calls and explosions, to scare wildlife away and mitigate possible damage to aircraft during take-off and landing.
