No, this is not a report written by me (I am not able to write in English with this degree of... sophistication: I am French)... A Scottish friend of mine is responsible for this
) But the account is quite accurate and complete.
Thanks for your contribution anyway.
I've run simulations on DEMs (digital elevation models) of the area and found suitable (so as to reflect sunlight toward the observer) areas on several mounts in the vincinity. Still trying to credit with pilots the possibility of strong sun glints from sloppy, high altitude glaciers.
