"Towers Watson: Estimate how many planes there are in the sky.
What, the sky just here? Or the whole sky, everywhere? And do you just mean big planes like 747s, or are you including itty-bitty one-seaters, and training flights for learner pilots? What about remote-control planes? Those drones the Army uses to spy on people? They could have thousands of those and none of us would know. That’s a very wide question. I’m going to say six. No, 14."
