The 1954 French flap:

"It is a huge and worthy work which needs to be urgently carried out because the witnesses of year 54 start to seriously age (if they did not already disappear!) and it is high time to question them again to compare their current testimonies with their former one. I know several groups which wrote to me to announce the startup of this work. One can only applaud and recommend that they remain careful in their critical research and not to hesitate to put side to side the two different versions, without judging by themselves which is the correct one. It would perhaps unconsciously privilege the current tendencies of ufology... at the expense of the historical truth, since nothing proves that the version currently given thirty years after the facts and with the erosion of the memory is the right version of the events. Thus it is best to juxtapose testimonies, letting to those who will read and study these texts in the future the care to shape an opinion, for one must be very conscious that this work is not for ourselves."
