B28FI Nuclear Bomb Wings Over the Rockies Air and Space Museum

Mk28/B28FI 
Hydrogen Bomb 

The Mk28 hydrogen bomb, although first produced in 1958, remained an active item until 1991. It was designed to be carried by various fighter and bomber aircraft (F-100, F-104, F-105, B-47 B-52, and B-66). This weapon is capable of a ground or air burst and may be carried internally or externally, with a free-fall or parachute retarded drop, depending upon its configuration.

The W28 small diameter, light weight thermonuclear warhead in M28 became the most versatile and widely used design ever adopted by the United States. This tactical and strategic thermonuclear bomb had the longest US service duration (33 years) and 2nd largest production run of any U.S. weapon design with over 4500 produced.

The Mk-28 employed the "Building Block" principle, permitting various combinations of components to be combined: 

B28EX- Carried externally by F-100, F-105, and F-4; no parachute 
B28RE- Carried externally; equipped with one 4-ft. pilot chute and one 28 ft. ribbon chute. 
B28IN- Carried internally by B-52 and F-105; no parachute. 
B28RI- Carried internally; equipped with one 4-ft. pilot parachute, one 16.5-ft. ribbon extraction chute, one 64-ft. solid chute, and one 30-in. stabilization chute. 
B28FI- Carried internally; equipped with one 4-ft. pilot chute, one 16-ft. and one 24-ft. chute.

On 17 January 1966, during a mid-air refueling operation, a U.S. Air Force B-52 bomber collided with a KC-135 tanker over the coast of southern Spain near the village of Palomares. Both aircraft were destroyed and 7 of the 11 crew members onboard perished. The B-52 carried four B28 nuclear weapons. Parachutes deployed for two weapons. One bomb was recovered intact from a dry river bed east of Palomares and the other was recovered intact from the Mediterranean seabed 5 miles offshore 80 days later. Parachutes failed to deploy for two weapons which underwent high explosive detonation. One landed less than a mile west of the village and the other landed at the eastern edge. This resulted in various amounts of radioactive contamination over 558 acres.

The Historic Boettcher Mansion, located in Golden, Colorado, is a stunning example of Tudor Revival architecture. Built in 1917, it was designed by the renowned Denver architect, Jules Jacques Benois Benedict. The home was built for Charles Boettcher, a German immigrant who made his fortune in the sugar industry.

The two-story mansion sits on a hilltop with views of the Rocky Mountains and downtown Denver. The exterior of the building is constructed of stucco, stone, and half-timbered wood, and features a porte cochere and a grand stone terrace. The interior of the mansion has intricate woodwork, plaster ceilings, and stained glass windows. There are seven bedrooms, seven bathrooms, a grand staircase, and a formal dining room.

The grounds of the mansion are just as impressive as the house itself. The landscaping was designed by Saco De Boer and includes a walled garden, a reflecting pool, and a pergola. There is also a carriage house, a tool shed, and a greenhouse.

The Boettcher Mansion is now a museum and is open to the public for tours. It is also available for special events and private functions. The Historic Boettcher Mansion is a testament to the beauty and craftsmanship of Colorado's past and is a must-see for anyone visiting Golden.
