Bill Sweetman Takes a Look at Textron's Scorpion

My first reaction to photos of the Textron Airland Scorpion was not positive, I will admit. The tandem cockpit, twin canted vertical stabilizers and slender straight wing made it look too much like a Citation wearing a Super Hornet costume for Halloween.

From an operational viewpoint, it seemed to be at risk of falling between two stools: not that much more survivable than a light attack aircraft in the AT-6 or Tucano class, and, in a reconnaissance mission, able to carry the same kind of sensors as a special-mission King Air, but more expensive to buy and fly, and with one very busy weapon-systems operator in the rear seat.

Before I went to Farnborough, I ran those twin tails past some people I know who really design airplanes. The Scorpion passed this test: The fuselage was wide enough, I was told, to cause problems with body slipstream blanketing the tail at high angles of attack. Two tails could be lighter than the tall single fin that would be required to get some fin area above the body wake. (I’m looking at you, M-346.)

Next, it was a matter of venturing to the Textron display, located somewhere in Surrey, to talk to Textron Airland’s president, Bill Anderson, and chief engineer, Dale Tutt.

In person, the Scorpion is quite big. At 21,250 lb. max takeoff weight, it is about the size of the M-346 or a Citation Excel, it carries a 9,300 lb. useful load, and it stands well clear of the ground. As a jet, it offers much greater speed and altitude capability than a King Air or AT-6, Anderson points out.

Sweetman Might be on to Something: USAF Neither Confirms nor Denies Texas Mystery Plane


The identity of what appears to be a blended wing-body aircraft type photographed over Amarillo, Texas, on March 10 remains uncertain, with the U.S. Air Force declining any comment on the aircraft.

Three aircraft were observed flying in formation southwest of Amarillo around 4:20 p.m. CDT, by photographers on the fence line of the city's international airport. IbOne of the aircraft could be a B-2, but the clearest color photos and monochrome images enhanced (for contrast and resolution) with commercial software suggest a blended shape with a straight trailing edge. Steve Douglass, one of the photographers and an experienced aircraft observer, says the aircraft were “larger than fighter-size” and appeared similar in wingspan to commercial traffic.

The formation was not using Mode S transponders, according to a review of records at the Flightradar24 air-traffic-tracking site. Radio transmissions apparently associated with the flight were intercepted and recorded, possibly including the call sign “Sienna.”

An Air Force representative in Washington responded to queries about the aircraft, and about flight activities at that time and place, with the statement “I have nothing for you,” a phrase long associated with responses to queries about classified programs and operations. The 509th Bomb Wing at Whiteman AFB, Mo., home of the Air Force's B-2 fleet, says that none of its aircraft were operating near Amarillo on March 10. However, test units have also flown B-2s.

The fact that three aircraft were in formation suggests an aircraft that is operational or close to reaching that status. The unidentified aircraft are not likely to have been examples of the Northrop Grumman stealth reconnaissance drone known as the RQ-180 (AW&ST Dec. 9, 2013, p. 20) because unmanned air systems are seldom flown in formation of any kind. Likewise, the Lockheed Martin demonstrator that is reportedly being built to support the Long Range Strike-Bomber program is likely to be a one-off product.

Sweetman @ AvLeak Claims Plane Chasers in Texas Find Mystery Aircraft


As far as I know, this sort of thing has happened only once since 1956.

That was when British magazines started getting eyewitness accounts and grainy photos of the Lockheed U-2, then operating out of RAF Lakenheath on its first spy flights over the Soviet Union. Classified programs have been exposed in all sorts of ways since then - for example, the A-12 Blackbird was disclosed under a degree of pressure - but until the RQ-170 Sentinel was seen at Kandahar in 2007-09 there has been no such aircraft photographed before it was declassified. (And in the case of the RQ-170, the operational security people were not trying too hard.)

With that in mind, let's look at the photos taken by Steve Douglass and Dean Muskett of an aircraft seen over Amarillo on March 10.


hmmm.  I remember the doughnuts on a rope pix from the late 80s early 90s as well.
