Cellphone Signals Don't Come From Space??? Or Do They???

Date: 1/10/2013

This hard thing to admit, but...

...I never turn off my electronics when I fly.

I may pause whatever I'm listening to and take my headphones off, but that's it. I don't even switch my phone to airplane mode.

From time to time I even try to text just to see if it works.

This last flight home I was playing with my phone and noticed that there was no signal, I jokingly thought, "Maybe we're going too fast to get a signal."

I looked to the sky and thought, "but for reals, we're closer to space, shouldn't the satellites, right..."

Then I realized.

I don't think I know how cellphones work?
