The Lockheed L-18 Lodestar was a passenger transport aircraft of the [Vous devez être inscrit et connecté pour voir ce lien] era.



Design and development


The prototype of the [Vous devez être inscrit et connecté pour voir ce lien] L-18, which first flew in 1939,
was constructed from one of a batch of [Vous devez être inscrit et connecté pour voir ce lien] which had been returned to the manufacturer by[Vous devez être inscrit et connecté pour voir ce lien] after a series of crashes of L-14s.

The fuselage was lengthened by 5 ft (1.5 m), enabling the fitting of two more rows of seats and hopefully making the
aircraft more economical to operate.

However, most US airlines were by then committed to purchasing the [Vous devez être inscrit et connecté pour voir ce lien], and Lockheed found the Lodestar difficult to sell at home.

A total of 625 Lodestars of all variants were built.

Operational history

African Airways (21), [Vous devez être inscrit et connecté pour voir ce lien] (12) and [Vous devez être inscrit et connecté pour voir ce lien] (9) were the biggest airline customers.

Lend-lease aircraft were used by the [Vous devez être inscrit et connecté pour voir ce lien] as transports.

After the war Lodestars returned to civilian service, mostly as executive transports such as Dallas Aero Service's DAS Dalaero conversion, [Vous devez être inscrit et connecté pour voir ce lien]'s Learstar (produced by PacAero), and Howard Aero's Howard 250.

A few of the latter were even converted to tricycle undercarriage.

---------------------------------------------------------------------

The C-60 is a twin-engine transport based on the Lockheed Model 18 Lodestar.

During World War II, the Army Air Forces used the aircraft for training and for transporting personnel and freight.

First flown in 1940, the Model 18 was originally designed as a successor to the Lockheed Model 14 and the earlier Model 10 Electra.

The Army began ordering military versions of the Model 18 in May 1941.

Depending upon engines and interior configuration, these transports were given C-56, C-57, C-59 or C-60 basic type designations.

Lockheed built more C-60As for the AAF (325) than any other version of the military Lodestar.

After the war, many military Lodestars were declared surplus and sold to private operators for use as cargo or executive transports.

The C-60A on display was flown to the museum in 1981.
