XB-15 (Boeing 294)

Hi

I just wondered if anyone has any information or pictures on the XB-15 other than what is on the wikipedia page for it - http://en.wikipedia.org/wiki/Boeing_XB-15 ?


p.s. Wasn't sure whether to post this in the cargo or heavy bomber section, as was originally designed to be a bomber!

    from the Boeing site:http://www.boeing.com/history/boeing/xb15.html
     
    XB-15 Experimental Bomber
    The mammoth Boeing XB-15 began in 1934 as a design study for the Army to see if it was possible to build a heavy bomber with a 5,000-mile range. When it made its first flight, it was the largest and heaviest plane ever built in the United States. It was so large that the crew could go through passages in the wing to make minor repairs while the airplane was flying.
    Because a long-range flight, powered by the engines of the time, took several days, the crew had bunks to sleep on between shifts. The XB-15 had been designed for four 1,000-horsepower liquid-cooled engines, but because those engines were not available in time, it was powered by 850-horsepower engines. Nonetheless, it set several load-to-altitude records, including taking a 31,205-pound payload to 8,200 feet on July 30, 1939.
    Because the lone XB-15 was an experimental airplane, it did not serve as a bomber during World War II. The military converted it into a cargo carrier, designated the XC-105.

    There was a great article in the Air Force Museum Friends Journal either last year or the year before. I'll try to dig it out. Dave

    It appears from the article that "Grandpappy" as the men who flew the XB-15 called it, was sent to Panama where it was used to ferry cargo to areas such as the Galapalogos Islands, Lima, Miami, Port of Spain, and Brownsville. The last day of its operational career came on 12-7-44 when a crack was found in the left outside landing wheel and there was no replacement. It was later scrapped in Panama although there is a rumor that the fuselage is still intact buried in a landfill.

    Hello,
     
    Thanks for the reply and the link. I notice that the Wikipedia article states that this unit also operated other 'one-offs' Has anyone any information on other rare types used by 20 TCS?
