In reply to Luca Signorelli:
Ok, I've a bit more time now so here's some additional detail on today's news. As reported before, the Augusta 193 twin engine of VdA rescue service (SAV) managed, exploiting a sudden clear window, to fly twenty minutes around the summit plateau, trying to get a clear view of the missing climbers position.
(Yesterday the Chamonix PGHM managed, in the middle of the storm and at insane personal risk, to winch down few minutes two guides on the top of Pt. Whymper. These had just the time to look briefly around, drop the survival kits then ask to be retrieved before all hell broke loose)
The VdA crew was made of a specialist and two guides. The initial idea was to locate the position of the climber, drop the guides in location, and then send in another chopper with the medical team if required. The pilot had to negotiate four different layer of clouds, at the same time keeping close enough to the mountain to try spot something in the upper plateau. However, there was absolutely nothing there, except for the survival kit dropped by the PGHM yesterday (that has been left untouched). No trace of the missing climbers. They tried however to close in enough to leave the guides there (they were prepared to dig in in case the weather prevented their retrieval), but the wind was just too much - 25 knots coming from SW. So they had to return.
Another attempt whas tried 30 minutes later, but the weather closed in almost immediately. The PGHM has tried twice to near the GJ from north today, but despite the better visibility in the French side, this time they're having the worst deal with the fohen winds coming from Italy (normally is the other way round, stormy weather in France and fohen in Italy)
Tomorrow morning, as soon as it lights, there will be another attempt from Aosta.
The other big news today are that Olivier's friend, coordinated by Olivier's brother Bruno, will attempt tomorrow morning to climb the Jorasses from two different routes, the Normal route from the Boccalatte and the Hirondelles ridge from the "new" Gervasutti hut. The rationale is to "sweep" any possibile area where the two missing climber may have been stranded. It's however a seriously risky plan, as the avalanche risk is big, and the Hirondelles are totally plastered, and everyone hopes they will not add new problems to those already in place. In any case, I guess it may be dreadful for Bruno and Olivier's friend to sit down doing nothing.
Ok, here's it for today.
