The plane into building idea was floating around in the sixties and was reported to Nixon in 1969 in an investigation into the terror underground. Someone tried to hijack a plane out of Baltimore (I think) in the early seventies with the aim of hitting the WH.
Nuke power plants and large dams are our biggest vulnerabilities. If Lake Powell “surged” to the Gulf of CA I imagine it would take Mead along with it. Maybe we should lower the impounded water levels a bit until Islamofascism is wiped out.
Actually, after all these years of running muddy water into it, Lake Mead is mostly mud. The sudden surge of what water is impounded would cause havoc downstream for awhile but the newly exposed soil would support quite a few farms until the dam could be repaired.
