Today the Sierra rocked!
The forecast said that it would be an excellent wave day from Inyokern to Minden with a cold front gradually bringing lots of moisture toward the south.
We launched at 0636 PDT into blue skies and as expected did not find any lift at Cache Creek or Kelso so we did not shut down until we were high enough to glide to the hot spot near Inyokern.
The wave was initially weak and gradually improved as we went north. By the time we got to the first wave cloud north of Lone Pine, the wave was excellent. From Lone Pine to Minden I have never seen the wave better. The wind was perpendicular to the average course line and the wave clouds perfectly marked the route so the transitions were no problem.
Our ATC clearance to Minden was where the clouds rapidly increased so we turned back south. I had declared a 300 km out & return course from west of Big Pine to west of Inyokern. We started as we passed Big Pine and had a good run going south. South of Owens Lake the clouds ended and the wave got soft so we abandoned the record run and headed north.
The wave was getting even better with increasing clouds. We were able to get back to Minden where we turned.
Passing Big Pine southbound we restarted. This time the rotor clouds extended almost to the turn. We completed the out & return course at 240.9 kph (149.7 mph) to claim the US National Multiplace Motorglider Record for the 300 km O&R. The lift was so strong approaching the finish that we made an upwind excursion so as to not go above the ATC altitude limit.
By the time we got back to Mammoth the thick cap cloud was protruding into the valley. We tried to skirt our wayaround it but were having trouble maintaining our ATC block altitude so we turned back south.
We were careful to be high when we got to Inyokern because we were facing a strong headwind for the final glide back to Rosamond.
Thank you, Cindy for arranging the Sage 2 and glider areas, Joshua Approach and Oakland Center for the outstanding ATC service, and Roger, Akiko, and Jackie for crewing.
Think Big Wave!
