Event Description:

REPORT 1 [safety officer edits]

There was about 12 wings on scene and all flew within a very small air space in front of the take-off site for getting lift.

The traffic was very busy indeed.

I was turning left at the edge of the lift zone and saw the yellow wing [PILOT A] in front of me facing each other.

The yellow wing kept turning right and we both avoided collision.

After we had flown in parallel for a second, another blue wing [PILOT B] appeared at the other side of the yellow wing in opposite flying direction.

Their wing tips collided (< 0.5m) and then twisted.

I noticed the pilot of the yellow wing tried to open the reserve but failed due to downwind.

The blue wing of upwind opened the reserve successfully and landed nearby the take-off site.

Afterwards, the yellow wing spun and crashed to the slope nearby a big boulder within few seconds.

And some pilots noticed the accident at the take-off site went down and assisted the crashed pilot within a minute.

Committee Response: (if any )

Having had the opportunity to communicate with PILOT B and having seen video footage of the accident i am glad to say this has been a lucky day for the pilot(s) involved indeed.

Not wanting to put blame for who did what and who was in the right or wrong, i believe there is a lot to be learned from this unfortunate accident.

By my counting there were at least 8 gliders operating in the vicinity of the take off. Some were Ridge Soaring and at least one was attempting to Thermal.

Again, without trying to blame anyone, it is important that everyone understands that the right of way rules apply especially when ridge soaring, IE anyone with the ridge on their RIGHT has the right of way. ( CLICK )

I ACTIVELY DISCOURAGE pilots thermalling in close proximity to others who are ridge soaring.


the pilots involved both threw their reserves:

PILOT B had the following sequence: accident = 0sec, throw reserve = +4sec, inflated = +8 sec, landed = +13sec.

PILOT A apparently did not get a proper reserve deployment. I am awaiting the report from this injured pilot to see if there was a technical reason as to why the reserve was not deployed ok. Pilot A was wearing an harnbess enclosed in a cocoon.

So until the information arrives please take aboard the caution information. IF there a lots of pilots airborne, please exercise extreme caution and know you r right of way rules !!
