Fly on the wall
From the giant to the minuscule. When the media talk about drones, I don’t know about you but I am usually picturing small plane sized objects flying around the planet taking pictures or firing shots.
But it turns out that some of them are actually tiny. This is the FLIR Black Hornet, which is as big as a cellphone and weighs 33 grams. Its role is to take HD photos and video so that soldiers can take fewer risks. In this case, size does matter.
