Looking at the HRRR charts WaltWX provided on his blog for the record attempt, my vote would be yes. There was a bunch of serious vertical motion in northern WY...which is where the incident occurred at 34,000 feet. USAToday article link follows. http://www.usatoday.com/story/news/n...lence/5575375/ Unfortunately not everyone was strapped into their seats on the 737 and some injury occurred. I wonder if Gordon and Hugh took any opportunity to scream as they rode their roller coaster!? Brad. |

This is odd, as usually the air is extremely smooth at high altitude in the laminar flow of the wave. Correct as far as it goes, I guess...and this is exactly what I once thought until I went from laminar to "WTF was THAT?!?" in an early-for-me wave flight up around 28,000 feet. Even did a serious "S" turn to look back for the jet I'd missed seeing violating my little bit of the wave window; nothing spotted. Mentally settled myself down from my fright, continued climbing for another thousand feet or so, then hit worse, more sustained turbulence - enough to convince me I was in over my head. So I descended to land and began some self-education. Short form is any time you're near the edge of a wave (bottom=rotor; edges/top=shearing) expect serious turbulence. Save for the rotor, the edges typically aren't visibly marked. "Top of wave? Don't they all just sorta peter out 'way up high'?" That's what I likely imagined prior to that flight. Truth is guys like the late Dr. Joachim Kuettner (discoverer of the wave and a long-time member of my club) assert that so-called 'trapped waves' (his terminology) are likely more common than the really big 'petering out' kind. My layman's understanding is trapped waves are the kind vertically constrained by wind shearing action. Subsequent to that first wave turbulence encounter, I had several more; each time proved something of an adrenaline generator for me. Eventually I decided height for the sake of height - no matter how sublime the views from 'way up there' - wasn't the lure for me it once was, and - lacking Gordon B.'s drive, and hence unable to effectively use waves for XC in my part of the intermountain west (Oh! for the days of the former 24,000' 'Positive Control' airspace of [for me] semi-recent yore) - waited to vicariously enjoy other's exploits. Congratulations to everyone involved in this (and all former) pioneering soaring flights, and "Thanks for sharing!" Bob W. |

Not necessarily. I remember having to take a test on this during a structures review session. Lots of rough stuff at high altitudes wherever airmasses collide. Google Clear Air Turbulence.

Nearly 48 hours later... Seems the flight isn't going on OLC?

Likely no OLC points for Gordo and Hugh for this flight. Maybe OLC can make an exception and permit its loading and points more than 48 hours after landing? Steve |

Or perhaps they could just make the .IGC file available publically on Dropbox, GoogleDrive or any number of file sharing properties?
