This aircraft was flown as a "McDonnell Douglas 188" STOL demonstrator in the northeast corridor in the US during 1968. It was not registered in the USA, but was operated by the French Air Force on behalf of McDonnell Douglas in full Eastern Air Lines livery, under its military serial 2 (callsign F-ZJRL, formerly coded "L"). The following year it was painted in American Airlines livery and flown on other routes. The aircraft returned to France in June 1969 and was then operated by the French AF coded 62-NB until withdrawn from use in 1974. McDonnell Douglas had obtained a license to build this in the US as the 188, but since the airlines showed little interest the project was aborted.
