The launch was fun. Alex was doing his usual great job lobbing us skywards, and when my turn came there were three or four other gliders on Hongrie, busy trying to scrape away. Alex towed me well above the wires on the top of the hill, and the next thing I saw was him doing an uncharacteristically  sharp dive, prompting me to a quick release.

"Did you see the other glider?", he asked over the radio. I replied that I hadn't. A detailed search of my immediate environment yielded no sightings, so I carried on with my flight and Alex set off for his next tow.

The good news was that I had been dumped into a 4-knotter which was enough to get me away from the cuvette via Jouere, Authon, Auribeau and the Blayeul.

I flew to the Cheval Blanc under completely blue conditions and was tempted to make my first visit south to the lac Ste Croix. The lure of the north drew me to turn left, rather than right, at the mountain and I headed up the parcours towards les Trois Eveches.

Lac de Serre-Poncon from 14,000ft

The parcours was working really well. I picked off a good thermal at la Blanche and carried on via Dormillouse to Morgon. Another thermal got me to 9,000ft, at which height the other two gliders that were keeping me company set off for Guillaume.

And then a quite interesting thing happened. A surge just to the east of the Morgon got me turning again, and again, until I realised that I was in some wave kicking off from the Ecrins. Switching my SeeYou mobile to its 2km scale I was able to return to the best lift again and again, finally topping out at a surprising 14,500ft.


Searching near the col des Terres Blanches

I cheerfully set off Guillaume-wards and was somewhat bemused to see my FLARM pinging me about a fixed obstruction ahead (that is, not a collision risk with another glider). Seeing no evidence of pylons and wires at 14,000ft, I continued with my search for the next piece of wave, but it wasn't until I was abeam of the col des Terres Blanches, having lost 3,000ft in the transition, that I picked up the next bar. I worked that for another 1,500ft, and the next ridge north, until I was in the lee of the main Pelvoux ridge. After some time, I managed to find some very strong lift at the head of the valley that took me once again back up to 14,500ft.


Mont Blanc, 100km away

I then headed west, along the Valgaudemar, the pic de Bure and other likely wave spots, but the day was getting late and it was time to return for home.

The following morning, I had a chat with Alex because I needed to understand what had happened during my tow today. It soon became apparent that what his FLARM was warning him about was a fixed obstruction, most probably the wires at Hongrie. Even though we were well above them, and I had received no such warning with my FLARM.

So, two false warnings from two separate FLARM units today. Faulty software? L' Armee de l'Air playing silly buggers with GPS scrambling? Answers on a postcard, please...
