MCDONNELL DOUGLAS DC-8 SUPER 61
The DC-8 was designed in 1955 as Douglas Aircraft's answer to
Boeing's highly successful Boeing 707, the first American jet airliner. It
offered an intercontinental range and seated from 105 to 179 passengers
depending on the airline's preference.
In 1965, there was a need for an intercontinental jet to carry large
numbers of passengers (over 200). At the time, the best competitor was still
the Boeing 707 -- the DC-10, 747, and L-1011 hadn't yet existed. The basic
DC-8 fuselage was stretched by about 36 feet. The new version, dubbed the
Super Series, was born.
There were three Super Series built. The -61 was the basic stretch
version. The -62 was stretched only 6 feet, but offered refinements in the
wing shape and offered tremendous range (8,000 miles plus). The -63 combined
the -62's improved wing with the -61's stretch, along with a refined engine.
Initial customers of the -61 series included Air Canada, Delta,
Eastern, Japan Air Lines, National Air Lines, and United Airlines. The -61
seated up to 259 passengers, and made its first flight on March 14, 1966.
It entered scheduled airline service on February 25, 1967.

The DC-8-61's handling is somewhat heavier than most commercial
