Douglas A-26B Invader

The Douglas A-26 Invader (B-26 between 1948–1965) was a United States twin-engined light attack bomber built by the Douglas Aircraft Co. during World War II that also saw service in Korea, Vietnam, the Bay of Pigs, and several other conflicts.  A limited number of highly modified aircraft (B-26K/A-26A) served in combat until 1969. The redesignation of the type from A-26 to B-26 has led to popular confusion with the Martin B-26.  Although both types used the R-2800 engine, they are completely different designs. The last A-26 in active US service was assigned to the Air National Guard; that aircraft was retired from military service in 1972 by the US Air Force and the National Guard Bureau and donated to the National Air and Space Museum. The A-26 was originally built in two different configurations.  The A-26B had a “solid” nose, which originally could be equipped with a combination of anything from .50 caliber machine guns, 37mm auto cannon, 20mm or even a 75mm pack howitzer, but normally the solid nose version housed six (or later eight) .50 caliber machine guns, officially termed the “all-purpose nose”, later commonly known as the “six-gun nose” or “eight-gun nose”.  The A-26C’s “glass” nose, officially termed the “Bombardier nose”, contained a Norden bombsight for medium altitude precision bombing.  The A-26C nose section included two fixed M-2 guns, later replaced by underwing gun packs or internal guns in the wings. After about 1,570 production aircraft, three guns were installed in each wing, coinciding with the introduction of the “eight-gun nose” for A-26Bs, giving some configurations as many as 14 .50 in (12.7 mm) machine guns in a fixed forward mount.  An A-26C nose section could be exchanged for an A-26B nose section, or vice versa, in a few man-hours, thus physically (and officially) changing the designation and operational role.  The “flat-topped” canopy was changed in late 1944 after about 820 production aircraft, to a clamshell style with greatly improved visibility.

    • Ownership history and uses are a little sketchy, but they must have been interesting since the aircraft was seized from drug-runners by T.L. Baker of the Potter Co. Sheriffs Dept in Amarillo on January 10, 1977. This occurred after a pilot had landed the aircraft on one engine and walked away from the airplane. This clearly made the authorities suspicious. A testament to this story is that at a particular air show a few years later, two gentlemen in dark sunglasses seemed rather intrigued by the airplane; finally one of the gentlemen approached a crew member and asked what color the aircraft had been before Ranger Wing acquired it. When told it was white with grey trim he   exclaimed, “My God it’s the “Grey Ghost! We chased that sucker up and down the Gulf Coast! Never could catch him. He’d drop down on the deck and throttle the engines up and leave us standing there!“. The two gentlemen were DEA agents.
