Short answer  ;-))

My welcoming the Vice-President of IBM Tod Groo and the President of IBM France Christian de Waldner at the Nice airport upon landing of the "1401" IBM company plane for an actual visit to the WWAM project.
According to FAA website registration, the N1401M is a "Beech 65 Queen Air" built in 1961. There is another picture of N1401M at "Air Britain Photographic Images", taken in Glasgow Scotland, August 1962:
According to Air Safety Network, on November 18, 1968, it reportedly "descended below published approach minimums and crashed in a river (2 fatalities, 6 occupants)." At that time, it was operated by Executive Air and stationed at Latham, NY. This "Boght Fire Dept" website shows rescue of passengers from a plane crash into Mohawk river near Albany on that day: :-(

" When I left the IBM French lab, the engineers and technicians wanted to make an usual gift I would remember... They crafted a wooden scale model of the 1401, enclosed it into a Plexiglass cover and organized a special ceremony during which they offered it to me..
I is still in my home in its original form, and I have been using it for many many years as a coffee table in my living room..
" Very early in the program, in August 1955, and because the French IBM President Christian de Waldner had been instrumental in getting the project started, the US group came to Paris in order to evaluate the potential housing? problem which was serious after the war.. Here is a picture taken during the "tour" we made of the Paris suburbs on housing hunt.
Top left is Christian de Waldner President of IBM France. Forth from the left is Ghertman, French Lab manager at the time. I am fifth from the left. Jacques Maisonrouge who was the French Head planner for the project at the time is seventh from the left. Bill Christensen who was the US Head planner is eighth from the left. Gene Estrems is on the top right.
