This is great. I haven't seen Yuri this excited since Dean Potter flew from the Eiger to Grindelwald. As for Yuri's end game, he has made that pretty clear. He wants wingsuit designers to use a more scientific approach to design, including proper testing instrumentation. He's been around for along time, so I think he has given up on trying to persuade the people in charge of that, and is left with just posting here.

I had never seen that technique before. I have psycho packed my canopy the last ~450 jumps, so I know that pretty well. Jay Mo's technique is most interesting to me in that he rolls the canopy but manages to keep the bridle attachment point outside the roll, looks like the weight of the bag pulls the apex down and keeps it ahead of the roll as it is made. I can imagine with a slippery canopy this method would be harder than a conventional psycho pack. Controlling the cocoon while lifting it off the floor and then rolling it up would take some getting used to. As Jay shows, keeping it tight against your body (basically using the body like a floor surface) would be key to keeping the canopy under control while it is rolled up.

I will say there is something that feels different about a manufacturer copying an idea or feature from another vs. making an exact clone of a product. Neither are necessarily against the "rules", but I would not view a reproduction of someones complete product as something I would be proud to own. I would rather see tweaks or incorporations of features, so that both competitors products offered a different experience. I see what Yuri proposed as different than that, because he wanted to copy an out-of-production item. And speaking of out-of-production copies, I watch Jeno Leno's Garage on Youtube now and then. Pretty cool that with a high-res 3D scanner and a 3D printer he can make copies of most auto-parts, very handy for restoring old cars.

Contacting the manufacturer with your measurements and the rig is often useful. Sunpath can give you the ideal rig dimensions that will fit your body, and if you have the serial number for the rig they can double check the sizes. They can tell you if the rig will be a good fit or not, or you can post the values here and people can tell you if you will need some harness adjustments, etc. Seth It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less".

That is not a valid comparison. Cheating on a test is against the rules. The relevant comparison would be breaking into your competitors facility and stealing his research ideas before they see the light of day. If an idea is not patentable, it is fair game, and we as consumers are better off for it. Ford buys a Honda car and tears it down to see what they can improve or use. I heard PD bought a Leia and tore it apart before building the Peregrine. Sometimes one company as a single good idea, but the rest of the product or quality is not good. If a competitor can incorporate that and produce a superior product, the consumer wins. This happens ALL THE TIME.

It is not counterfeit if it is not passed off as the original. If the design is not patented or copyrighted, what is the problem making a copy? Existing skydive manufacturers do that all the time, changes in container design, canopy design, wingsuit design, all have points where key features were first put on one companies model, then showed up on competitors models. For another example, the generic drug industry has saved many people a LOT of money by making out-of-patent copies of drugs. Are you the kind of person who insists on name-brand drugs, even if they are much more expensive?

Good thing the couch was there to break her fall. Yep, cats are weird. I still don't understand how she can easily hop over to that ledge, but still can't hop back. Now she justs deliberately jumps down and lands on the couch. It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less".

At my wife’s request I made a cat video a few months ago. I had built a ladder so our cat Olive could get to an upper window ledge, and she got into a spot she had trouble getting down from. https://www.youtube.com/watch?v=fs1nKXThvvk It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less".

Those are bluetooth trackers which are completely useless for skydiving. They have a range of 50' or so. It could be useful if you could attach a phone to a drone and fly a grid pattern. Look at the phone app afterward and see if it found anything. It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less".

It's a Disney movie, for chrissakes! OTOH, they could just have everyone dress like Donald Duck or Winnie the Pooh and no one would even notice. That does remind me of the another famous movie / comic question, "how do dr. banner's pants stay on when he increases in size by 200% and turns into the hulk?" His shirt shreds to pieces, but those pants must be really stretchy. It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less".

the fake part seems lame, but also completely understandable. I did the Chicago Naked Ride this year, I think it is the biggest in the country, 2000-ish people and a police escort. Weird to think my naked self got recorded ~1000 times judging by how many cell phones spectators where holding up.

This is the Late Late Show with James Corden / Perris Valley tandem jump video. Very well done. The bit with the creepers was great, and the "big box little box cardboard box" no contact flying plan was hilarious.

Yeah that is what I think was in effect before the big bumps in 2003, A-license was 20 freefall jumps. Then it went to what it is now, 25 total jumps. It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less".

I was just starting out in 2003 which was the big change that I recall. I remember the scramble for the D and Cs, this change feels small in comparison, and I seriously doubt it will have much impact on IAD retention rates. Can someone tell me what the A-licence requirements were in 2002? Google is letting me down on finding them.

Again, I'm not saying communication is dumb. Communication is great. What I am saying is "opening at 5k should not affect the delay taken by the following group" and therefore not telling them is not a safety issue. there are two safety concerns I have seen raised: 1. tik168 is saying you need to give extra delay to account for the fact that once open if the person flies up the flight line they could fly into the airspace of the next group. I ran some numbers. First thing that stands out is this is not a concern if you are followed out by free-fliers, as they will catch up to you by the time you finish deploying, so if you do fly up the flight line you are flying over top of them. Actually they could give you a smaller delay if they knew you were pulling higher as the break-off spread would occur below you. (I'm not saying anyone would do that of course) (If they need to give a really long delay, still not a problem as see below) If you are followed out by a tandem with video, we need to consider the video flyer. How much closer will the canopy be flying for X seconds up the flight line? And what should X be? Let us assume the TI always plans to give solos 400ft of space. How long will it take our solo to cover that distance? With a 20mph speed, 13 seconds, so our vidiot could be in danger if the winds required a very long delay. But, and this is a very important point, the same collision risk exists no matter what the opening altitude of the solo is. If the solo opens at 3k and flies up jump run for 13 seconds, he will be under the vidiot too, the same position. In fact, he would most likely be closer at 3k, as in really strong winds typically the winds at 4.5k are stronger than 2.5k. I'm just a little depressed that some people can't understand the physics of this, or think the concern of running into someone while you are deploying is not a big deal. 2. Baksteen mentioned that seeing canopies above him freaked him out and caused a cutaway. This is a valid point, but I think the argument is a weak one. IMHO this goes in the "communication is good, but you should be prepared to handle your shit regardless" It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less".

If you are coming down on top of me, I am not sure which is better, for one to be in freefall and one under canopy, or both under canopy which would lead to an entanglement or wrap. IMHO the rules for horizontal exit separation have been written in blood. It is extremely important to maintain those rules for the safety of all jumpers, and if someone is incapable of doing so, he/she is putting any jumper in the previous group at risk, regardless of pull altitude. If it actually is that important, the rule should be spelled out somewhere, if someone opens above XX altitude, you MUST give them YY additional delay. Just telling them what is going on is not enough. It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less".

Yeah, maybe it was 3500. Dont get hung up on the number, you see the only point I was making, sometimes 4500 is against the rules. It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less".

True. My only point was if the other groups exit how they are supposed to, opening at 5k is not a problem. So if we are to not make assumptions, the correct conversation with the following group is not "I'm letting you know I'm pulling at 5k", it is "What exit delay are you giving me? 5 seconds? Not enough, with these winds you need 8. Don't short change me. Thanks!" The same exit delay for 3k opening is the appropriate one for a 5k opening, imho.

one I heard vanessa bayer tell on a podcast: It's moose hunting season. A moose hunter is walking in hilly terrain. He sees a hiker a long way off, and the hiker sees him and yells to him, "don't shoot me, I'm not a moose!" The hiker goes over a hill. A while later he comes back into view, closer this time. Again he yells at the hunter. "don't shoot me, I'm not a moose!" Again the hiker disappears into the woods. Some time later he rounds a bend and is right in front of the hunter. He loudly says: "don't shoot me, I'm not a moose!" The hunter shoots him. The fallen hiker looks up at the hunter and says, "why did you shoot me, I said I wasn't a moose." The hunter replies, "oh, I thought you said you were a moose" It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less".

What if the tandem had a separate video flyer? Doesn't matter. I only mentioned tandem altitude b/c above that you really start to land late, and it does make sense to let the pilot and wingsuiters know there will be a canopy in airspace it normally wouldn't be in. But as well all know, it is horizontal separation that matters between groups, not vertical. If I end my skydive early, whether intentional or not, none of the other freefall groups should be affected. Even wingsuiters should be on a flight path well off the standard flight line. It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less".

Why is that important? I can't think of a reason why it would affect the actions of any other group. Reasons I can think of is if after opening someone is looking around counting canopies they may wonder why they are 1 short (because it is 2k ft above them), or it is a good habit because some DZs and boogies have rules about not opening above 3k, and announcing your intentions to do so will give others a chance to tell you that is not allowed. But if I was at a DZ where it was allowed, I would not feel the need to announce my opening altitude, if I was under Tandem opening alti.

Yeah it is important to plan out the whole layout so you know how you will be balancing the tiles at the edges of the wall or floor. I am a big fan of not having less than 1/2 a tile width along an edge. I find that using a laser to keep a tile line straight is easier than a chalk line, because I am constantly putting mortar over the chalk line. It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less".

250 sq ft is a big ass bathroom. They probably think you are made of money! There are I'm sure others who have done more, but I have 6-7 tiling jobs over the years, usually 60-100 sq ft at a go. The last job was a complete remodel of my master bath, including a full tiled shower with dryset mortar base, electric heat in the floor and waterproofed floor. I used a mix of Kerdi and Kerdi like waterproofing method. Don't have much advice, but it is pretty easy to do if you are handy, 1. get a good how to tile book, read it several times until you are familiar with all the steps. 2. buy quality tools including a good tile saw. You are saving a lot of $ doing it yourself, put some of that towards good tools. 3. If you have another area to tile it may be good to practice on a less important area first. 4. For me, grouting is always the hardest part to get right. 5. Make sure the base is solid and as flat as possible, especially if you are using larger tiles. Use patching / leveling compounds to get it flat. It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less".

It is still not an interesting distinction. Just because a design allows for human operation does not mean it is capable of operation in fully automatic mode for the vast majority of its life. You are arguing semantics, and that is not a helpful thing to do. If your definition of fully autonomous means no human controls, then your definition is different that everyone else's, and you can't have a useful conversation. It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less".

Ok. But I don't think it is an interesting problem. You want a car to drive for it's entire service life (10 years) without a single human help event before you say the fully autonomous car is a reality. I don't care when that standard is met. If once or twice a year someone has to help remotely I'm fine calling that car fully autonomous. Waymo is planning on having remote support people, but it is not a 1-1 plan. If you have 1 person "monitoring" 10 cars, from an economic standpoint you are still getting significant benefit from the technology. That point is coming soon.
