Why not send the drone downwards?

Good thinking.

Honestly I didnt even thought of that while watching )))

But seriously - that was solution right there. Why would she send drone to diner when she could done that.....

Hmm. I think they didn’t have the drone at first (it was inside the backpack that fell down on the antennas). And then they needed the one remaining phone to control the drone.

The moment they thought of sendign the phone down in the shoe i thought doing it with a drone would be far better option, but alas that never came to their minds.
