The '''Lockheed Model 18 Lodestar''' is an American passenger transport aircraft of the [[World War II]] era, developed as part of the Model 10 Electra family, specifically from the [[Lockheed Model 14 Super Electra]].

==Design and development==
Sales of the 10–14 passenger [[Lockheed Model 14 Super Electra]], which first flew in 1937, had proved disappointing, despite the aircraft's excellent performance. It was more expensive to operate than the larger [[Douglas DC-3]], already in widespread use.{{sfn|Francillon|1982|p=135}} In order to improve the type's economics, [[Lockheed Corporation|Lockheed]] decided to stretch the aircraft's fuselage by {{convert|5|ft|6|in|m}}, allowing an extra two rows of seats to be fitted.{{sfn|Francillon|1982|pp=185-86}}

The prototype for the revised airliner, designated Model 18 by Lockheed, was converted from the fourth Model 14, one of a batch which had been returned to the manufacturer by [[Northwest Airlines]] after a series of crashes. The modified aircraft first flew in this form on 21 September 1939, another two prototypes being converted from Model 14s, with the first newly built Model 18 flying on 2 February 1940.{{sfn|Francillon|1982|pp=1398, 186}}

A total of 625 Lodestars of all variants were built.

==Operational history==
[[File:LockheedLodestar.jpg|thumb|Lockheed Lodestar]]
[[File:Lockheed Model 18 Lodestar over Houston,1947-48.jpg|thumb|Lockheed Model 18 Lodestar over [[Houston]], 1947 or 1948]]
The Lodestar received its [[Type certificate]] on 30 March 1940, allowing it to enter service with the first customer, [[Mid-Continent Airlines]] that month.{{sfn|Francillon|1982|p=186}} As hoped, the extra seats greatly improved the Model 18's economics, reducing its seat-mile costs to a similar level to that of the DC-3, while retaining superior performance. Despite this, sales to US domestic customers were relatively slow as most US airlines were already committed to the DC-3, with only 31 Lodestars going to US airlines.{{sfn|Francillon|1982|p=187}} Overseas sales were a little better, with the biggest airline customers being [[South African Airways]] (21), [[New Zealand National Airways Corporation]] (13), [[Trans-Canada Air Lines]] (12) and [[British Overseas Airways Corporation|BOAC]] (9); another 29 were bought by the [[Royal Netherlands East Indies Army Air Force]]. Various [[Pratt & Whitney]] and [[Wright Cyclone]] powerplants were installed.

When the [[United States]] started to build up its military air strength in 1940–41, many American-operated Lodestars were impressed as the C-56. This was followed by the construction of many new-build Lodestars which were flown by the [[U.S. Army Air Forces]] as the '''C-60''' and by the [[U.S. Navy]] and [[U.S. Marine Corps]] as the '''R5O'''. Lend-lease aircraft were used by the [[RNZAF]] as transports.

One was purchased in 1942 to serve as Brazilian President [[Getúlio Vargas]]' personal aircraft. This aircraft was specially designed for that purpose and had 11 seats.

After the war many Lodestars were overhauled and returned to civilian service, mostly as executive transports such as Dallas Aero Service's '''DAS Dalaero''' conversion, [[Bill Lear]]'s '''Learstar''' (produced by PacAero), and Howard Aero's '''Howard 250'''.<ref name="Janes 65 p244">Taylor 1965, p. 244.</ref><ref>{{cite magazine|title=Have You Seen? Twin Feathers|magazine=[[Flying (magazine)|Flying]]|date=January 1954|volume=54|issue=1|page=40}}</ref> A few of the latter were converted to tricycle landing gear.

While the surviving [[New Zealand]] NZNAC aircraft were sold back overseas in 1951/52, six more were later imported and converted for [[aerial topdressing]].

A single Lodestar served with the [[Israeli Air Force]] during the [[1948 Arab-Israeli War]].

A number of skydiving operations in the United States used Lodestars during the 1970s and 1980s.

==Accidents and incidents==

On the 28th of March 1941 a [[South African Airways]] Lockheed Lodestar, on a flight from Windhoek to Cape Town flew into a cliff next to the sea near Baboon Point close to [[Elands Bay]], in thick mist, with total loss of life of all on board (pilot and six passengers). Notable amongst the passengers was Rear Admiral GW Hallifax, who was the first director of the South African Seaward Defence Force, the forerunner of the [[South African Navy]]. Some parts of the wreckage are on display at the [[Elands Bay Museum]].<ref>https://sanavymuseum.co.za/2021/03/28/into-the-mist/</ref>

On 5 January 1948, a [[South African Airways]] Lockheed Model 18 Lodestar (registration ZS-ASW) touched down at [[Palmietfontein]] too far along the runway for it to stop before running off the end. The undercarriage was ripped off and the hull damaged beyond repair. There were light injuries to passengers but no fatalities. <ref>

In 1949, a Lockheed Lodestar in airline service in [[Australia]] crashed immediately after takeoff. All 21 occupants died in the crash or the ensuing [[conflagration]]. The cause of the accident was determined to be that the center of gravity was behind the rear limit. It is also likely the elevator [[trim tab]] was set for landing rather than takeoff.<ref>Job, Macarthur.

On 4 September 1962, a Lockheed 18-56-24 Lodestar operated by the Ashland Oil and Refining Company crashed near [[Lake Milton, Ohio]]. The flight was in-route to [[Ashland Regional Airport]] (KDWU) from Buffalo Airport, NY. Eleven passengers and two crew-members were killed. Investigation determined the crash a result of a malfunction of the electric elevator [[trim tab]], which caused the loss of the plane's right wing during flight.<ref>{{cite web|url=http://aviation-safety.net/database/record.php?id=19620904-0|title=ASN Aircraft accident Lockheed 18-56-24 Lodestar N1000F Lake Milton, OH|first=Harro|last=Ranter|website=aviation-safety.net|access-date=4 April 2018}}</ref>

On 21 August 1983, a Lockheed L-18 LEARStar operated by Landry Aviation, Inc. crashed near [[Silvana, Washington]]. The flight was a planned parachute drop carrying two pilots and 22 parachutists. Nine parachutists and two crew-members were killed while 13 were able to parachute to safety after the pilots lost control and entered a vertical descent from 12,500 feet. Investigation determined the crash a result of a failure of the operator and pilot-in-command to assure proper load distribution during the parachute drop.<ref>https://ntsb.gov/investigations/AccidentReports/Reports/AAR8406.pdf {{Bare URL PDF|date=March 2022}}</ref>
