Air Force Magazine has an interesting article on one of General Eisenhower's personal transport aircraft during WW II (well, interesting if you're an aviation buff, which I am, sorta). The first few grafs from said article:
Note the article sez "wartime rarity," not unique. General Hap Arnold, chief of staff of the wartime Army Air Forces had one, too. General Arnold got his personal B-25 before Ike got his, actually. From another article (link below) on B-25 executive transports:As Supreme Allied Commander in Europe during World War II, Gen. Dwight D. Eisenhower needed to be able to travel—quickly—to meet with top alliance leaders and field commanders and get a close-up view of the unfolding war.
Eisenhower had an eclectic collection of aircraft at his disposal for a variety of uses, but only one was specially made for him. It was a heavily converted B-25 Mitchell medium bomber, built and modified by North American Aviation, the same company that produced the B-25s that attacked Japan in 1942 in the famous Doolittle Raid. Eisenhower's B-25—serial No. 43-4030—is poorly documented and deliberately so.
The year it was built, American P-38 pilots in the Pacific executed a daring, long-range mission to shoot down a bomber known to be carrying Japanese Adm. Isoruku Yamamoto, who had planned and carried out the 1941 Pearl Harbor attack. His death was a severe blow to Japan's strategic effort and morale. Army censors did not want German pilots to be able to repeat that success by shooting down Eisenhower, and so photography of his aircraft was severely restricted—especially because it had a unique profile.
Although by early 1944, B-25s were rolling off the North American-operated Kansas City plant at a sustained pace of about 300 per month, a VIP version of the Mitchell was a wartime rarity. Serial No. 4030 came to be known as RB-25J(3), denoting that it was a rebuilt airplane and only the third Mitchell to be specially modified.
The second B-25 modified by North American belonged to USAAF General Henry "Hap" Arnold- visiting the Inglewood facility at Mines Field one day, Arnold got to see the Whiskey Express and as the Chief of Staff, he decided he needed one, too. This was 1943 and production was rapidly accelerating in the B-25 program, so it was easy to divert a B-25C from production to be fitted out by North American to a similar standard as Whiskey Express. After the war, General Arnold's personal transport was purchased by Howard Hughes who used for another twenty years before it was retired.Most interesting. While the Air Force Magazine article is a good read, the second article ("The First B-25 Mitchell Executive Transport") is much more comprehensive and detailed.
The same year Arnold got his own B-25, a B-25J was taken off the production line in Kansas City and flown to Inglewood on a "secret" mission. Tail number 43-4030 was fitted out to become the personal transport for General Dwight Eisenhower. Unlike Arnold's B-25 which had olive drab upholstery, Ike's Mitchell had a more stylish blue interior. Clamshell doors were fitted to the nose for easy access to the extra communications and navigation equipment and more floor space in the aft fuselage was created by moving the gunner's aft hatch further back, giving the rear cabin more seating and a drop leaf table. Overhead luggage racks were also fitted and extra fuel tanks were fitted to the bomb bay to give it more range. Officially it was designated an RB-25J to hide its true nature as Ike's personal transport, but as the war in Europe progressed, it was redesignated CB-25J and when Eisenhower moved up to larger aircraft as the Supreme Allied Commander, the CB-25J was passed on for use by lower ranking generals and was used by the USAF postwar until it ended up in the possession of the South Dakota Air and Space Museum where it can be seen today.
