A stationary camera aboard the International Space Station recorded a flash of red laser light being fired, apparently toward Earth but more probably toward something in orbit above the atmosphere that cannot be seen. The reason is that the atmosphere would most likely diffuse the laser pulse, rendering it unreadable on the ground.

This appears to be an authentic piece of video. What we are probably seeing is not a UFO firing a laser pulse at Earth, but a satellite using a laser communications system that is classified by whatever country owns the two satellites involved.
