Tartiflette Fan, can’t see your FB page. As far as I can work out from the local paper they had fuel contamination to deal with so the runway was unusable. The crane appeared on the runway late afternoon and the whole operation seemed to take less than an hour. You can see it all on the altiport webcam time lapse function.
