B-52 bomber mistakenly carried nuclear warheads on domestic flight: report

WASHINGTON (AP) — A B-52 bomber was mistakenly armed with six nuclear warheads and flown for more than three hours across several states last week, prompting a U.S. air force investigation and the firing of one commander, Pentagon officials said Wednesday.

The plane was carrying Advanced Cruise Missiles from Minot Air Force Base, N.D, to Barksdale Air Force Base, La., on Aug. 30, said the officials, who spoke on condition of anonymity because of a Defence Department policy not to confirm information on nuclear weapons.

The missiles, which are being decommissioned, were mounted onto pylons on the bomber’s wings and it is unclear why the warheads had not been removed beforehand.

High probability this thing flew over western IA.
