Sorry Don You snooze you lose :) Just me?

Two of the Pentagon’s four specially reinforced ‘Doomsday’ planes, designed to withstand the heat from a nuclear blast, have been grounded after being damaged by a tornado.

The Air Force said Friday that two E4-B Boeing 747s were damaged when a tornado whipped through Nebraska’s Offutt Air Force Base with little advance warning on June 16.

Built in the 1970s during the Cold War, the planes are essentially flying command centers that can refuel in the sky and are designed to remain airborne for days on end in times of crisis.

The two damaged ‘Doomsday’ planes were reportedly parked in hangars during the storm, but their tails were exposed to strong winds.

The Air Force has four E4-Bs, which also shuttle the secretary of defense around the world.

‘Two E-4B National Airborne Operations Center aircraft stationed at Offutt AFB received storm damage,’ Air Force spokesman Colonel Pat Ryder said.

Not including the damage to aircraft, the tornado caused an estimated $7million to $10million in damage to the base facilities, 55th Wing spokesman Drew Nystrom told the Omaha World Herald.

Additionally, seven RC-135 reconnaissance planes suffered minor damage in the tornado and another needed an inspection.

The E-4B is a 747 that has been reinforced to protect against the electromagnetic pulse from a nuclear blast and is shielded from a thermal blast.
