Altitude... The third dimension?

[Preacher]

The dust has settled, you've spent a year creating a permanent, private base, you've got your crops planted, your rubbish piled neatly away from your door, your water capture, equipment and bug out vehicle close to hand and you're in your recliner, dozing in the sun, with a tankard of homebrew, feeling very pleased with yourself for getting everything so beautifully organised and your kids are playing happily because Daddy's got it all under control.

Then... One of the kids points out a microlight, probably spotting, (possibly mine) at 3,500 feet, heading away from you.

With your current plan (be honest now)...How likely is it that you Are a cross on my chart?
