Last Passenger Flight of TWA Constellation L749A N6020C (CN2658)
I'm trying to clarify when TWA Constellation L749A, N6020C (CN2658) made its last domestic passenger flight:
In "Constellation Survivors" by Ralph Petterson, dated September 29, 2003, page 4 indicates it was a flight in May 1967 from JFK, New York to St. Louis, Missouri.
On the airliners.net website, a caption beside a Bob Garrard photo of the same plane reports that the last flight was on April 6, 1967, but doesn't list the departure and arrival cities.
Another 'source', Wikipedia, states that "the last scheduled passenger flight in the 48 states was made by a TWA L749 on May 11, 1967, from Philadelphia to Kansas City, Missouri (Wikipedia cites 'Germain 1998, page 89' as the source).
The Wikipedia reference is to a L749 and not to a L749A, and lists different cities than the Ralph Petterson article, further adding to my confusion.
Hopefully someone out there can confirm when the last passenger flight of TWA Constellation L749A N6020C (CN2658) actually took place, and between what two cities.
