Lockheed L-049 Constellation
US airliner with 4 piston engines, 1943

The Lockheed L-049 Constellation is the first model of the Lockheed Constellation aircraft line. It entered service as the C-69 military transport aircraft during World War II for the United States Army Air Forces and was the first civilian version after the war. When production ended in 1946 it was replaced by the improved L-649 and L-749 Constellation.
History
Design and development
In June 1939, Howard Hughes, the owner of Transcontinental & Western Air (later Trans World Airlines and abbreviated TWA), held a meeting at his Hancock Park residence in California. Jack Frye (then president of TWA) attended along with three executives from the Lockheed Aircraft Corporation which included designer Clarence "Kelly" Johnson. During the meeting Hughes expressed his concerns for what he called the "airliner of the future". Lockheed's airliner under development at the time, the L-044 Excalibur, did not meet the requirements.
When the meeting ended with Hughes and Frye, the executives immediately started on improving the Excalibur to meet Hughes' expectations. One idea was to use the Wright R-2600 engines in place of the proposed Wright GR-1820. It was decided instead to start from scratch using some original characteristics of the Excalibur.
Begin with the source’s own compact description: “Lockheed L-049 Constellation” is uS airliner with 4 piston engines, 1943. The dossier treats that line as a proposition to test through Lockheed, L-049 and Constellation, not as a finished interpretation.
Why this record matters
The phrase “uS airliner with 4 piston engines, 1943” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q134215. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1946, 1939 and 1820.
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.
