Douglas DC-3

The first airliner that made money carrying passengers alone.

The all-metal DC-3 entered service in 1936, crossing the US in about 15 hours with 21 passengers. By 1939 it carried roughly 90 percent of the world's airline traffic. Over 16,000 were built including military versions, and some still fly today.
