There is a scene in the Tom Hanks movie about Sully the heroic airline pilot who landed in the Hudson River (IIRC). There is a government hearing, and Sully is on the spot for not actually taking his plane back to the airport. They ran simulations, you see, and the FAA had pilots in Sully's situation and they managed to get back to the airport after all their engines failed -- so why didn't Sully?
Hanks, as Sully, gets them to admit that their test pilots knew what the problem was going to be ahead of time, immediately turned toward the airport at the first moment of trouble (spending no time at all on problem analysis), had no lives at risk during their action -- and still had to practice the maneuver 17 times before they managed to land at the airport.
Political activists like to state that "this is easy" -- but they have to create absolutely ideal circumstances to "prove it".
I trust the Fence. I don't think it will be easy to get through.
Thicker steel and rebar in the concrete and you won’t be doing that with hand tools.
