Lockheed Model 18-07 Lodestar, Vantaa

The Lockheed Model 18 Lodestar twin-engine passenger plane made its first flight on September 1, 1939, and operation began in 1940. Customers were offered modifications for 15-18 seats, and there was also an extended version for 26 passengers. The aircraft lost out to the famous Douglas DC-3 in economy, so airlines bought Lodestar reluctantly, before the war only 96 aircraft were built, mainly on orders from small airlines in Asia and Africa. The military also did not show much interest in the aircraft, only the US Navy and Coast Guard ordered three aircraft for the needs of the command staff.
