Lodestar

The Lockheed Lodestar served as an airliner as well as military transport during WWII. Airlines such as National, QANTAS, BOAC and South African among others operated the type. While the USAAF, RNAF, RAAF and Netherlands East Indies Air Force operated them out of what is now named Indonesia till they were over-run by Japanese forces. The scope and complexity of these war time operations are beyond the remit of this site, though I do have extensive details of ALL Lodestars no matter what their 'uniform' was. Please contact me with any particular queries you may have [Michael Zoeller].

The following info was on the WWW. Some of it is well known, some not. I've included it in it's entirety:
"During World War II, the U.S. Navy (USN) acquired 68 Lockheed Model 18 Lodestar transports for its use and for use by the U.S. Coast Guard (USCG) and U.S. Marine Corps (USMC). In USN service, the Model 18 Lodestar was designated R5O. Delivered between May 1940 and October 1943, the last R5O was struck off the inventory in June 1950. The Model 18 was developed because of problems with its predecessor, the Model 14 Super Electra (designated PBO and R4O, q.v., in USN service). The first commercial operator of the Model 14 was Northwest Airlines which purchased eleven aircraft. Three of these aircraft crashed between May 1938 and January1939 causing the flying public to lose confidence in the aircraft and Northwest returned the Model 14s to Lockheed and purchased the slower Douglas DC-3 (R4D, q.v., in USN service) in March 1939. (During the same period, five Model 14s crashed outside the U.S., one each in Canada, England and the Netherlands and two in Rumania.) Recognizing that it had a big problem, Lockheed began work on a replacement for the Model 14. The new aircraft used the wings, engines and tail surfaces of the Model 14 with a redesigned, stretched fuselage. Although very similar to the Model 14, a new model number, 18, was assigned and the aircraft was given the name Lodestar to distant it from the previous Electra family. The stretched fuselage improved directional stability and allowed two more rows of seats in the aircraft thereby solving another problem of the Model 14, i.e., high seat-mile cost. The resulting aircraft was a twin-engined, all-metal, twin-tailed, mid-wing monoplane with the main landing gear retracting into the engine nacelles. The tail wheel did not retract. As with the Model 14, the aircraft was equipped with leading-edge slots and Fowler flaps. Seven models of the aircraft were manufactured, the difference being the specific Pratt & Whitney or Wright engine that powered the machine. The specific engines were identified by a two numeric suffix to the model number, e.g., Model 18-07s were equipped with two Pratt & Whitney Hornet S1E2-G engines. The Model 18s could accommodate either 15- or 18-passengers depending on whether or not a flight attendant and full galley were provided. The Model 18 prototype was actually one of the Model 14 Super Electras that Northwest Airlines had returned to Lockheed. With a new fuselage, this modified aircraft made it first flight on 21 September 1939. Two other Model 14s were also modified before the first production Lodestar made its maiden flight on 2 February 1940 and received an Approved Type Certificate (ATC) on 30 March 1940. The first airline to operate the Model 18 was Mid-Continent Airlines of Kansas City, Missouri which began service in March 1940 as soon as the ATC was awarded. Mid-Continent eventually purchased four aircraft. Other U.S. airlines purchasing the aircraft included Continental Airlines (5), Dixie Airlines (2), Inland Airlines (1), National Airlines (3), Pan American World Airways (17, all to Pan Am subsidiaries, i.e., 2 to Pacific Alaska Airways and 15 to Panair do Brasil) and United Airlines (4). Overseas operators included the governments of South Africa (1), Norway (3) and the Netherlands East Indies (29); overseas airlines included Air Afrique (5) of Mozambique; Air France (3); British Overseas Airways Corporation (BOAC) (9); Venezuela's Linea Aeropostal Venezolana (LAV) (1); Brasils Navegacao Aerea Brasileira (2), South African Airways (21); and Canada=92s Trans Canada Airlines (12) and Yukon Southern Airways (2). The U.S. began a buildup of its military forces in 1940-41 and both the U.S. Army Air Forces (USAAF) and USN impressed a number of Model 18s for their use. These impressed aircraft were (1) being operated by U.S. airlines, (2) were being built by Lockheed or (3) had been ordered by the airlines but production had not started. The USNs impressed aircraft are described below; the USAAF impressed 102 aircraft designating them C-56, C-57, C-59 and C-60. Most of these impressed aircraft were returned to their owners or sold by 1944. The first true military aircraft was the C-60A ordered by the USAAF on 5 February 1942 as an 18-seat paratroop transport; the 324 C-60As consisted of 52 C-60A-LOs, 45 C-60A-1-LOs and 227 C-60A-5-LOs. Lodestars also served with the Netherlands East Indies Air Force, Royal Air Force, Royal Australian Air Force, Royal Canadian Air Force, Royal New Zealand Air Force and South African Air Force."

My interest is what happened to these planes once they left military or frontline airline service. Some passed on to smaller operators such as KarAir in Finland, Panair in Brasil, Linjeflyg and Swedair in Sweden, NZNAC in New Zealand and Canadian Pacific Airlines. While many passed on from military store yard to any one of the plethora of post war conversion centres springing up in the USA. Lodestar modification centres include: Dallas Aero Service, Remmert-Werner, St. Louis, MO, Executive Aircraft Services Inc., Dallas, TX, L.B.Smith, Miami, FL, Grand Central Aircraft, Glendale, CA, AiResearch and Pacific Airmotive both in the Los Angeles area. And of course there was Lear and Howard Aero. After numerous tweaks and prods the Lodestar would re-emerge as a corporate transport, for some it was just a coat of paint and some passenger seats for others it was a lengthy re-build. The task of detailing the non Lear and Howard Aero conversions would be a web site of it's own, something I might do in my retirement (that's a 15 year wait!). Here are a few tit-bits of information about three of the smaller aircraft modification centres:

Minnesota Airmotive Inc.
Requested in late 1954 to fly 8 x L.18s from Leon, Spain to Minneapolis, MN. At this time the aircraft were being made airworthy in Spain. Six of the aircraft were: 2144, 2147, 2148, 2151, 2152 and 2157. The other 2 x were unknown at the time. All were originally with the RAF and had been sold to the Spanish Air Force. 8 x reges were requested for these aircraft, 22.11.54 by the FAA in Europe. Reges were allocated 8.12.54 thus: 2144=N9926F, 2147=N9927F, 2148=N9928F, 2151=N9929F, 2152=N9930F 2157=N9931F, N9932F allocated to c/n 2068, 15.12.54 and N9933F allocated to c/n 2020 also 15.12.54. All aircraft were to be converted to executive use once in the USA. Minnesota Airmotive created a 260mph, $275,000 'Super Lodestar' fitted with 85 USG capacity tip-tanks for extra range as well as introducing extensive aerodynamic improvements, first aircraft to be converted was N58MA (c/n 2157 see above). A large number or former European registered L-18s had been acquired in the Spring and Summer of 1956 by Minnesota Airmotive perhaps in anticipation of orders for their Super Lodestar. Despite a country-wide demonstration tour in late 1956 and a doubling of its production capacity at its base at Wold Chamberlain Field Minnesota Airmotive was only to complete two of these conversions. It would be fair to say that many potential customers must have been put off purchasing the Super Lodestar due to its high cost, as the cost of an executive Lodestar was only in the region of $135,000 - $150,000.

Spartan Aircraft Co.
Spartan based in Tulsa was initially a manufacturer of training aircraft in the 1930s, post war it became a modification centre specialising in Lockheed's big twins the Ventura and the Lodestar. The bulk of their work involved the Ventura but at least 9 Lodestars were worked on too. The company is still in existence today as an avionics/aeronautics training school.

Dallas Aero Service
For the aviation department manager with a tight budget and a tired looking Lodestar, Dallas Aero Service had their Dallaero Lodestar. The $5,000 modification gave the aircraft an extra 30 mph speed increase according to their sales literature of the time and they claimed that the conversion could pay for itself within a year of normal operation. In the mid 1950s operating cost for a Lodestar was approximately $200 per hour (compared to $184 ph for a DC-3, $279 ph for a Ventura and $383 ph for a B.23) and average utilisation would have been in the region of 50 hours per month. A total of 22 aircraft were converted.

Hamilton Aviation
Hamilton Aviation in Tucson, Arizona under the guidance of former Lockheed employee Gordon Hamilton licence built six executive 'Lodestars' by converting Hudson bombers in a similar manner to that in which the first three L-18s were converted from L-14s. Hamilton's former employer was amused by his proposal and the FAA inspectors were amazed by what he'd done. With help from Clarence "Kelly" Johnson, Lockheed's technical genius, licensing and certification was granted. Proof of the strength of Hamilton's work is the fact that many of his conversions were still in service until the late 1970s
