I would dearly love to make the trip to Py for the anniversary, because my sister was the lead hostess on the plane, but due to a recent stroke (not severe, but bad enough), I have to miss out. When I was there in 1998, I met an English woman who along with her husband, ran a wine cellara little further down the valley (possibly in Sahorre), and she had kept all the local newspapers from the time, and they had a lot of information. I also met the son of the mayor at the time of the crash, and he was also very knowledgeable, he also used to be a mechanic for Alain Prost the racing driver.
At the time, that time I met a number of very friendly people in and around the village, though I haven't been back since then, I'm sure they are just as friendly now, and more so if you at least try to communicate in French.
