Does anyone realize the danger?

Scenario: You fall, break your leg, can't move, you crawl into your campsite, your phone has no coverage, and you are running out of food. How do you signal a helicopter or low flying plane, your only hope of survival?

With a brightly colored tent of course!
A bright tent could save your life!
How could you see a camo tent from the air?
I think a camp accident is probably a greater danger than a bear is.
