Douglas DC-3: Διαφορά μεταξύ των αναθεωρήσεων

The DC-3 was engineered by a team led by chief engineer [[Arthur E. Raymond]], and first flew on [[December 17]], [[1935]] (the 32^nd anniversary of the [[Wright Brothers]] flight at Kitty Hawk). The planeaircraft was the result of a marathon phone call from [[American Airlines]] CEO [[C.R. Smith|Cyrus Smith]] to [[Donald Douglas]] requesting the design of an improved successor to the [[Douglas DC-2|DC-2]]. The amenities of the DC-3 (including sleeping berths on early "DST" -- Douglas Sleeper Transport -- models and an in-flight kitchen) popularized air travel in the [[United States]]. With only three refueling stops, eastbound transcontinental flights across America taking approximately 15 hours became possible. Westbound trips took 17 hours 30 minutes due to typical prevailing headwinds - still a significant improvement over the competing [[Boeing 247]]. Before the arrival of the DC-3, such a trip would entail short hops in commuter aircraft, during the day, coupled with train travel overnight.
