Why would an airborne camera be able to pick ground-based lasers up easily? Wouldn't you need to fly directly between the satellite and the ground terminal?
Same goes for laser-guided bombs - those home in on where the laser pointer is pointing, not the pointer itself.
Deflection. It's pretty easy to spot a laser pointed straight up, because it's deflections create a visible trail of the beam. Have you ever shined a laser pointer in a foggy room, or seen the lightshows that do so? That.
