I’m trying to imagine being at that height and no cell phones were hitting any distant towers. You think their range would be very extended with line of sight to a tower.

A typical cellular antenna does not radiate upward at all:

As you can see above, the vertical pattern is a narrow beam toward ground (from the height of the tower.) The intent is to deliver power to where the customers are.

Wasn’t there a crash recently where the passengers were texting their final goodbyes?

Got it, thanks.

In any event, it appears as though this was a mass murder event for whatever the motive.
