LNG Tankers are offloaded in Boston, MA. within sight of the Tobin bridge and close enough to everything to make such an event a total disaster. Back when the shipments were first proposed it was estimated that the area at least to the Prudential center would be wiped out. Large parts of Cambridge, Somerville, and Chelsea would also be taken out. The former Charlestown Navy Yard would be wiped off the planet. Likewise Quincy Market. Mass General Hospital would be well within the total destruction zone and If the event took place at the dock there would be even greater devastation.
Stay well - Stay safe - Stay armed -Yorktown
Then it must be assumed that the LNG tankers are given "nuclear weapons grade" security, yes?
