The plane had only just broken free of the earth's gravity and was a few hundred feet off the ground when Greg and Mark saw the black dots ahead of him rise up from the grass beyond the runway fence.

They moved like a swarm of killer bees and quickly split into two groups. Each group maneuvered in the sky directly in front of each of the oncoming 737's engines.

"What in the hell...holy shit!" Greg shouted and looked eyes as wide as dinner plates at Mark. The plane's cockpit careened past the dots at over 400 miles per hour, and in that second, time slowed. Greg looked out of the cockpit window aghast at what he saw.

Drones.

Hundreds of them.
