Author’s Note: This is a reprint from my club newsletter about a weekend trip to Talihina, OK in February 2013. For more information on ridge and wave soaring in Oklahoma, check out http://talihinasoaring.com/Talihina_Soaring/Welcome.html.

The toll booth operators in Oklahoma are getting smart. They wanted to know if I was headed to a glider convention. Jeff Beam had gotten out of work a few hours earlier on Friday and was ahead of me on the turnpikes on our way to Talihina, OK for the weekend. Jeff has had the Apis down there several times this winter and I had been there in December with Kate the Cirrus and was returning for a second try. Forecasts were encouraging with a cold but unstable thermal day for Saturday and stable air but strong south winds on Sunday.

Saturdays forecast lived up to expectations. High temperature for the day was a chilly 43°F but there were thermals to over 4000 ft. Talihina is at 680 ft. The day started off alright for Jeff and I who launched first but some high cirrus quickly moved in. Andre de Baghy had launched in his HpH 304 Shark with jet engine sustainer but no one else was brave enough to take a tow with the newfound shadow over the valley. However Jeff and I were able to mark thermals for each other and stay aloft comfortably. We found a little lift off the Kiamichi Ridge to the south and some more over the Potato Hills to the west of the airport. Andre had flown east along the Kiamichi, reasoning that the light northwest wind would push the thermals to the ridge. He got about half way to Mena before turning back. We all joked that we would’ve been that brave if we’d had a jet engine on board too but when he did get low he tried to start the jet only to find that his battery was too low! So he was back to being a pure sailplane and managed to soar his way home. Jeff and I stayed local to the airport. Later in the day after the sun came back out the rest of the gliders started launching and I found a good thermal to over 5000 feet off the slope of Buffalo Mountain, now absorbing direct sunlight. I landed about the time the last guy launched and within an hour or so everyone was back on the ground.

We enjoyed a good supper at the Mexican place in town and all looked forward to a good ridge day with strong south winds forecast for Sunday. However it looked like the winds above the inversion would be more westerly and the inversion would rise as the day went on. This would cap potential wave action but we were still hopeful for a long day running Buffalo Mountain. Jeff was first to launch with Omri next in his HpH 304CZ. Jeff wasn’t having much luck staying up on the ridge and Omri radioed that he was returning immediately. I was next in line to launch but decided it might be a good idea to wait. The wind was just too light and Omri said it was pretty westerly at ridge top. Jeff had scoped out the hang glider field on his way home in December and decided the ridge was either going to work or he was going to land there. Land he did and got to meet Ron the paraglider guy who gave him a ride back to the airport

Launch resumed around noon with Gerry Keiffer going first in the Duo Discus then me in Kate and everyone else after that. The ridge was working good and we had a good time flying along in a loose conga line. Everyone got along well and we shared the skies with some turkey vultures and bald eagles as well as a hang glider. There were a few thermals on the ridge but they didn’t go very high. We definitely weren’t getting high enough to make a run into the valley to try to contact wave. However, I started to get the very strong urge to go. The urge kept getting stronger and I had a good chance to test the new airbrake panels on Kate with a quick dive into the airport for a landing which brought much relief. Gerry had landed earlier and on his second ride flight requested a tow upwind to try to find wave and they found it just south of the Indian Highway Bridge. I quickly rustled up more money for the towpilot and lined up with a request to take me where he had taken Gerry.

We towed straight out to the South. The air was a little turbulent but definitely not strong rotor turbulence. As we got to the bridge at about 3700 feet we started climbing well. “This is it” from the towpilot and away I was. I initially ran a bit west and turned on the tracking mode on my Oudie which left a crumb trail of where I had been climbing, color coded for climb strength. There were no clouds marking the wave so this would be my only hope of staying in it.

After a few miles west I turned back east and noticed my groundspeed east was much higher. Jeff took a second tow to the wave and soon was in it. Andre, in the meantime, had motored across the valley but was having difficulty connecting. I ran east along the Kiamichi Ridge until I was over to about where the Rich Mountain ridge begins and then turned back west. I was averaging about 7500 ft and usually was averaging zero sink or weak lift or sink. Only a few times was I able to find sustained strong climbs for any extended period of time and I maxed out at 8500. I went west off the end of the Kiamichi and found some wave over Sardis Lake which has a short ridge on its southern border. Then I turned back east for another trip across the valley. This time I extended a little further east but as I got over Rich Mountain the wave started to elude me. It was 4:15 PM and I was still up around 8000 feet. I figured it would be nice to land by 5:00 so that I might be home by midnight. I left the wave and started a fast glide towards Buffalo Mountain for a lap or two on the ridge before landing. The ridge was still working but everyone had landed and so did I, just a few minutes before 5. The flight was an amazing experience, my first flight in wave, and covered 240 km on the OLC for the longest flight of the day in the USA.

Needless to say after such a great flight and a satisfying weekend I had no problems staying wide awake reliving the magic on the drive home and pulled in the driveway right at midnight. The excitement got me through a long day at work on Monday. I can’t wait to go back!
