Source-derived summary

The Welch OW-1 and the similar OW-2 were American three-seat open biplanes designed by Orin Welch in the late 1920s.

The OW-1 was powered with a 90 hp (67 kW) Curtiss OX-5 and the OW-2 was powered by a 150 hp (110 kW) Hispano-Suiza 8A, both of which were water-cooled V-8 aero engines.

Four OW-1s were built (NC817, NC4205, NC5105, NC6838), one of which was converted into the first of two OW-2s. The first OW-2 was later modified into a 5-seater, before being destroyed in a hangar fire in November 1929. The second OW-2 was given the civil registration NC11142.

Editorial summary

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1929—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Welch, OW-1 and 1920s providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Welch OW-1”, the useful work is to connect “1920s American aircraft” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Mar 26, 2026. The linked authority identifier is Q65077099. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1929.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
