Emsco B-8 Flying Wing
type of aircraft
The Emsco B-8 was a two-seat, single-engine, low-wing, twin boom experimental aircraft designed by Charles F. Rocheville in 1930 while he was vice president of Emsco Aircraft Corporation, Long Beach, California.
Development
Rocheville sought for a safe, fool-proof airplane with exceptional range, endurance, and payload. He intended to make a non-stop flight from Tokyo to Seattle with navigator Theo Lundgren, a distance of about 5,000 mi (8,000 km). The aircraft, registered NX55W, first flew on 17 April 1930.
By June 1930 it had been fitted with a 300 hp (220 kW) Pratt & Whitney R-985 Wasp Junior nine-cylinder radial engine. Development ended in November 1930 because of lack of funds and the B-8 was scrapped.
Design
Despite its name 'Flying Wing' the aircraft carried a twin-boom empennage with a single vertical fin. The two crew sat in open tandem cockpits in a central nacelle with circular cross-section, initially with a 165 hp (123 kW) Continental A-70 in tractor configuration. The nacelle ended in a jet-engine like 'exhaust' nozzle at its rear, which actually was an intake to a boundary-layer bleed system driven by the engine which blew air through spanwise slots in the rear part of the 'Flying Wing' in an attempt to increase the wing's performance. Another unusual characteristic of the design was its “reversed tricycle landing gear” with two main wheels under the front wing and a single aft wheel under the rear-end of the nacelle.
This brief starts where responsible research should: with the source description of “Emsco B-8 Flying Wing” as type of aircraft. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as type of aircraft. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 12, 2026. The linked authority identifier is Q24525627. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1930.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
