The postmark is 1973. The Douglas or McDonald Douglas DC-8 was built from 1958 to 1972. It was in competition with Boeing’s 707 in the new era of jet travel. 556 were made and a few are still in service. In August, 1961, this was the first civilian jet liner to achieve (for 16 seconds) supersonic flight.
Remember the song lyric, “a big 707’s set to go.” (Gordon Lightfoot,”Early Morning Rain”) “Big DC-8’s set to go” doesn’t scan as well…
