I've moved the following 50 consecutive posts (everything existing from that point on to date) discussing the 2018/03/23 Quest aerotow launch crash from "Releases" to consolidate them with this newly created "Quest Air" topic (based upon a 2018/04/16 Matt Pruett video in which a gold mine's worth of relevant / smoking gun evidence is revealed. (The last of those - from Brian - is what brought this video to my attention.) To skip over the old transplants and get to the new stuff starting at the top of Page 6:

Screwed the pooch a substantial bit doing the transfer. Brian caught it before/while I was realizing that there was something majorly wrong with the pictures. (Somehow managed to miss about a page's worth.)

Major overhaul yesterday. Try as one might it's IMPOSSIBLE to do the job totally right on the first pass on a project of this magnitude. Little gems inevitably get missed and details to which one initially perceives as having zilch significance can become totally epic as the analysis evolves with additional information, better understanding, older issues are recalled.
I replaced 102538 with 102443 (a similar but better from two and a half seconds prior nicely illustrating an issue) and amended the series with fifteen new stills which improved continuity and caught stuff I'd missed.
And that effort cost me another very long day - which ended in today's wee hours (with Yours Truly mostly blind). Total nightmare overhauling sequence numbers, time stamps, the archive, editing and proofreading relevant posts.
Note: I'll likely be making minor edits - like amending photos and narration segment transcripts - to the five video archive posts:

without notification as we're pretty much just talking about providing more convenient looks at, listens to what's been publicly available on the video since 2018/04/16. Nothing's really being added to or subtracted from.

Getting caught in the cart by your wheel
Davis Straub - 2018/03/28 11:54:07 UTC
Tipped up and over
A sequence of shots for a incident on launch:

http://c1.staticflickr.com/1/877/39383252930_69a1edef34_o.jpg
The right wing has been lifted. The pilot appears to be holding onto the hose on the right side and lifting the cart. The cart is heading off to the pilot's left side and not on the track that the cart should be taking behind the Dragonfly. The tow rope is pulling the pilot to the right. The prevailing wind had actually been a little bit from the left, but thermals can come through the field.
Two or more seconds (nine photos) later the pilot is no longer holding on to the hose on the right hand side (and doesn't appear to be holding on the left hand side either) as the cart has been dropped:

The glider is also now tipped forward as you can see by the fact that the tail is high off the back cradle. The pilot is pulled by the tow rope all the way over to the right in the control frame. You can see the tow rope still connected to him. The cart has gone way off to the left. The base tube appears to have slid off the left front cradle.
If you look at the left side of his base tube you can see that the left white wheel is below the height of the front tube of the cart. It may be caught under the tube. The glider is tipped up, and the base tube is just above the front cradles on the left (and quite a ways above on the right). This allows the left wheel to drop down to the side of the left cradle to below the front tube of the cart. If the wheel is caught under this tube, the pilot has no chance to recover.

The photos are being taken at a rate of 3 to 4 a second. This is the next photo. The glider's control frame is still jammed on the left side on the cart with the white wheel below the cart tubes . The glider and the cart are going in different directions. The pilot is reaching out to break his fall. He fractures his elbow with a dislocation. The glider is unhurt.

Two photos later. The left white base tube wheel is jammed into the left corner of the cart. with the base tube on top of the front cart tube.
If the angle on the cart was too high, he would have been stalled before he was able to be pulled forward and had the keel raised up to get out of the stalled angle.

Oh. An INCIDENT. So surely we'll shortly be getting a report from the relevant flight park. They're obviously taking extra time in order to make double sure they get everything absolutely right down to the tiniest detail.Tipped up and over
A sequence of shots for a incident on launch:
No fuckin' shit. It's tracking pretty much sideways to the pull from the tug. So how did that happen?
Like he's supposed to and everyone does?The pilot appears to be holding onto the hose on the right side and lifting the cart.
- Stupid cart.The cart is heading off to the pilot's left side and not on the track that the cart should be taking behind the Dragonfly.
- What Dragonfly? Who's driving it?
- Again... WHY?
No shit. He should be OK shortly because the weight shift will work to bring the high wing back down. Exactly like when you're foot launching and running under the high wing...The tow rope is pulling the pilot to the right.

...without any torque input applied through your hands. It's the sideways pull on the keel that gets the glider to respond in the desired manner.

WHOSE left, motherfucker? His or ours? (He means HIS. But he doesn't know what port and starboard mean so he can't make things unambiguous.)The prevailing wind had actually been a little bit from the left...
- No shit. Got that, people of varying ages? Thermals can come through the field. Who'da thunk?...but thermals can come through the field.
- I thought we'd learned from the Zack Marzec incident from just up the road a bit over five years ago not to tow in thermal conditions.
- So Davis gives us this bullshit statement and the people who don't know how to read Davis start assuming that this glider got rolled onto its wingtip by some monster thermal that nobody's confirming while all the gliders in the background are sitting around just fine.
- Note that there's no cart monkey...

...running the glider up to speed. And that if there HAD been it's an absolute no brainer that this glider would've gotten safely airborne.
And note the "ranch hand":

on the ATV doing cart retrieval duty.
- The idea that this crash was the consequence of a thermal putting things on the path south is absolutely absurd. And although a powerful gust of some kind could MAYBE lift a wing - although the only other weak example that comes to mind is John Claytor trying to launch at Ridgely on 2014/06/02 in that insane gusting crosswind - it could not POSSIBLY explain the cart tracking away from the tug at something around a 45 degree angle. What we're seeing here is the first on-the-surface rolling lockout in the history of hang glider aerotowing.

A Ranch Hand will assist you.
Dropped the cart but didn't release. Go figure. Must've been trying to fix a bad thing and not wanting to start over. Guess the tug driver was thinking the same thing 'cause I've heard they can fix whatever's going on back there by giving the glider the rope.Two or more seconds (nine photos) later the pilot is no longer holding on to the hose on the right hand side (and doesn't appear to be holding on the left hand side either) as the cart has been dropped:

(Note that the towline is lined up pretty much perfectly with the top wire of the chain-link fence in the background. But what we're seeing is indeed all towline.)
Really? I was under the impression that...The glider is also now tipped forward as you can see by the fact that the tail is high off the back cradle.

...If you fail to maintain the correct tow position (centered, with the wheels of the tug on the horizon), the weak link will break before you can get into too much trouble.The Wallaby Ranch Aerotowing Primer for Experienced Pilots - 2018/03/28
If you fail to maintain the correct tow position (centered, with the wheels of the tug on the horizon), the weak link will break before you can get into too much trouble.
Can't imagine why that wing hasn't come back down yet.The pilot is pulled by the tow rope all the way over to the right in the control frame. You can see the tow rope still connected to him.
Or why both pilots are still trying to salvage that tow.The cart has gone way off to the left. The base tube appears to have slid off the left front cradle.
Who gives a flying fuck at this point?If you look at the left side of his base tube you can see that the left white wheel is below the height of the front tube of the cart.
- My guess is that the wheels weren't set to line up with the tow in the first place.
- There was no cart monkey to ensure that the cart started rolling in the right direction.
- The pro toad douchebag on the glider had the usual zero possibility of blowing his easily reachable placebo release as the emergency situation progressed.
- The fuckin' douchebag on the Dragonfly didn't bother to squeeze the lever on his joystick.
Yawn...It may be caught under the tube.
- Or release. Right...The glider is tipped up, and the base tube is just above the front cradles on the left (and quite a ways above on the right). This allows the left wheel to drop down to the side of the left cradle to below the front tube of the cart. If the wheel is caught under this tube, the pilot has no chance to recover.

- Yeah Davis. Keep burying us with all this useless bullshit to keep us from thinking about how this cluster fuck was precipitated in the first place.
How very strange it is that he's not reaching out to blow his...5

I have never had a lockout situation happen so quickly and dramatically and had no chance to release as I have always thought I could do.

Jim Gaar - 2008/10/28 15:55:22 UTC
We always told towed pilots that the first 500 feet belonged to the tug pilot. They have enough to do to keep themselves safe.
He can't do anything to fix whatever's going on back there below five hundred feet because he's got trees to stay out of.Jim Rooney - 2008/12/11 18:45:01 UTC
Yup, the first 500ft are mine. Try to keep up. Your tugger generally REALLY wants to help you, and will do all that he can to do so, but he's got trees to stay out of as well.
Good thing he reached out to break his fall. No telling how badly he'd have been hurt otherwise.He fractures his elbow with a dislocation.
Cool. Somebody else will be able to fly it while this guy's on the mend.The glider is unhurt.
And that he was using a pro toad bridle. If he'd been using a three point the carabineer would've slid up towards the top and have REALLY hammered the glider into the ground.
And the towline and tow ring are recoiling obviously from a back end weak link blow. And note the conspicuously absent mentions of ANYTHING concerning the placebo release(s) and Infallible Weak Link. Even the separation - 'cause that would draw attention to the release and weak link issues.Two photos later. The left white base tube wheel is jammed into the left corner of the cart. with the base tube on top of the front cart tube.
...it would been:If the angle on the cart was too high...
- primarily due to the negligence of the launch crew.
- totally fucking irrelevant - as ALL gliders are set some degree of nose high and the glider will properly trim itself as soon as it begins to lift.
Bull fucking shit. He can pull himself way the fuck forward five minutes before he connects to the tug....he would have been stalled before he was able to be pulled forward...
The glider was undamaged - right? So why wasn't it set back on the cart to determine EXACTLY what the trim setting was? 'Cause Wallaby was in its usual total ass covering mode?...and had the keel raised up to get out of the stalled angle.
Meaning Wallaby. And funny the mention of the operation is also so conspicuously absent.Photos by Bob Grant.

...Wills Wing fin installed on the Wills Wing glider that isn't designed to be motorized, tethered, or towed? Like what Dr. Trisa Tilletti pretty much forced everyone to use at their now extinct AT operation in Michigan?
Pretty clever of you to have picked up on this warning sign that everybody at Wallaby - operators and fly-in participants - seem to have missed.
Asshole.
