As I was getting out of work, I looked up in the sky and saw what appeared to be a four engine plane, I looked at FlightAware and saw that it was a KLM 747. As I looked around the area, I noticed that a couple of planes were due to land at Willow Run, so I decided to head over there.
The Dassualt Falcon 20 was the first of a set of business jets designed by Dassault Aviation of France. This is the company behind the famous Mirage series of fighters. Development of this aircraft began in December of 1961. Originally it was going to have Pratt and Whitney engines but Pan American was interested and had them changed to GE CF700 turbofan. It would have its first flight in 1963 and the first production aircraft rolled off the line in 1965. It was used by French Navy and Coast Guard (amongst others). Production lasted for a total of 25 years and 508 planes were produced.
