the photo makes me wonder if i can toss a nylon rope tethered alloy aluminum grappling hook 45’ high above me vertically. then jog 10 or 20 miles through the desert to escape the BP. hmmm... i think i would probably get caught if i tried, lol...
“wonder if i can toss a nylon rope tethered alloy aluminum grappling hook 45’ high above me vertically.”
Of course, it is possible (a hook could also be launched with a crossbow, or other device). Ladders could also be erected.
Testers found it difficult to manually place grappling hooks onto the 30 foot barriers (the height of a fourth floor window ledge) - and they were Military Special Operators. So most people are not fit enough for such an approach.
But for those who are fit enough, they must first cross a cleared and alarmed 150 wide enforcement zone, under constant camera surveillance, monitored by unblinking artificial intelligence. Border Patrol will have high speed, all weather road to respond on both sides of the barrier, and new small Unmanned Aerial Systems (drones) have already recently been deployed in the area, to continue to track any infiltrators, until intercept.
It is surprisingly easy to not lose track of people running through, or hiding amongst the vegetation, from the overhead vantage point, augmented with night and heat sensing capabilities.
Once all the billion dollar heavy earth moving, concrete pouring and steel erection is complete (I know, I said erection...), the roads and lighting are completed, and all the technological instrumentation is activated; it is a relatively quick, cheap and effective upgrade to add a few rolls of concertina on top, which dramatically impedes rope and ladder attacks.
