the part about them sneaking in probobly faked. the crane operator most likly in on the stunt. totally whacked if the operator not in on it.

@BASE104:
Thanks for that explanation. I clarifies a lot of what I'm seeing as I obsess over these videos. It's so bloody compelling. Perhaps you can help with this observation: Most of the videos are mostly in slo-mo. Can you point me/us to some POV clips that are at full speed, the 100+mph these dudes are making? The vids make it look like there's so much time to adjust the line, but clearly this is not the case.

Alex Polli also has full speed videos.
Chris LaBounte
Horizontal speed is more like 120-150 mph...Correct me if I'm wrong.
Vertical speed in the 60's?

The redundancy is killing me. Who has sharp butter knifes?

I do,
Tradman comments: = splat sooner or later.
Eventually equals splat? is The BASE version of - yer gonna die - ?

Um TMC?
If that stunt happened that way you'd just have a bag of bones in a nearby pile. He'd be dead before the big block hit the ground.

It is barley worth watching once,
Twice? I'm gonna find something nice, the blond who went splat? Or did she? I forget. But She Had Trix in Spades

How come in Dubai they let people jump from buildings and in America it's a serious crime.
Are Americans insane?

I still have no idea why you wrote something about 120:1 when the obvious number for an sailplane would be infinity
I guess for the same reason you wrote about a suit being capable of 5:1 - just to talk sh!t, braj!
As for the 'obvious infinity number' how would that be computed in standard aerodynamic
equations when it is mathematically and physically impossible? Now, let's get back to
discussing something relevant like stagnation pressure or interference drag, shall we? You
gotta agree both are large reasons those rigs are rocks with wings.

I'd love to hear about that. Please make your point.
ETA: And your opinion on this would also be appreciated

An infinity glide ratio over a finite time period mathematically and physically impossible? Ok...
Why should that be computed in standard aerodynamic equations when it should be obvious that it is a dynamical system we talk about and not some steady state that can be calculated with standard equations?
Lets give an example. You fly a sailplane with 150 km/h, at distance x=0 and h=100 m you start to pull on the stick and continue to fly at h=100 m. At distance x=1000 m your altitude is still h=100 m and your speed is 130 km/h. Lets do some glide ratio calculations over the distance interval [0 1000] m.
delta x/delta h=1000/0 which can be called infinity (you can of course use epsilons and deltas and do a limit argument if you want that).

Yeah, listen to Ammon. He's current. I'm an old fart who has been out of it for decades. It was new when I did it, and we were constantly figuring it out on the fly with gear and technique.
Now, at least in non-wingsuit BASE, it can be pretty safe. Not all objects are equal, though. Some are more dangerous than others, but they know that. Risk is a known quantity now, and techniques and vastly superior gear make it safer, especially for the experienced people, who have FAR more jumps than any of us could have imagined back then.
The Dubai festivals were invite-only affairs. You had to be experienced and not have a bad reputation.
I added up the number of jumps held in Dubai once, and I came up with over 8000 without major incident. I think that one year the locals sort of organized it themselves, and there was either a fatality or a serious injury. I can't recall.
8000. That is a big number. These days, if they opened El Cap, and somehow could do it in that invite-only format, it could go on for years without incident. El Cap is that simple of a jump.
If I showed Ammon the early pack jobs, he would turn his head in horror. We did figure it out after a while, and it was close to the modern pack job. Other things were really crude, though.
