Drone came within 200 feet of airliner over New York at 1,750 ft

It wouldn't surprise me to learn that foreign governments and corporate spies are using drones in American airspace for reconnaissance as we speak.

• Radar cross section is to small
  • Any regular plane within 1000 feet would be in danger unless the on-board computer was designed to only accept something smaller than a Piper cub/equivalent
• No heat signature
  • Any regular plane within 500 feet would be in danger
  • 15 degree angle w/ respect to the sun is blocked out.
• Optics
  • At that range would require the SAM to draw a bead on the object before launch.
  • Can human eye see that far to locate something that small.
  • How else would one be able to aim the missile if you can not see where to aim.
    Slave to the radar - possible; not very feasible.

NOPE:

I've seen some videos purporting to demonstrate weapon-grade lasers taking down aircraft. Those would probably work pretty well on drones if the targeting was worked out somehow.
