Traffic at Paris-Orly Airport grew rapidly at the beginning of the 1950s. In the mid-1950s plans began for a new location near to Parisian airports. The potential locations were all less than 150 km from Paris, for example Melun, Pontoise, Coulommiers, Étampes, Reims, Évreux, Chartres, and Orleans. A report dated 20 May 1959 lists the disadvantages of a location too far from Paris. René Lemaire gave a report on 14June 1960 in which he supported a transfer to Toulouse. The "École nationale supérieure d'ingénieurs de constructions aéronautiques" settled in Toulouse in 1961 and the "École nationale supérieure de l'aéronautique et de l'espace" was also going to move from Paris to Toulouse. On the 15 June 1961 Prime Minister Michel Debré accepted the transfer to Toulouse. His successor Georges Pompidou confirmed the transfer in a letter dated 23 July 1963.
