The Plane that Flew Terry Lennox to Mexico:
The Long Good-bye, Chapter 5

"Nobody from L.A. wants to ride a DC- 3 over mountains when he can take a Connie and make it in seven hours to Mexico City."

Introduced in the 1930s, the DC-3 was a two-engine propellor airplane that carried twenty-one passengers and cruised at 190 miles per hour. It was once the most popular plane for domestic passenger service but by the 1950s had been replaced by four-engine aircraft such as the Connie (Lockheed Constellation), which could carry a hundred passengers and travel at over 300 miles per hour.
