//How accurate would you have to be? // |
|
| |
Fifty points for a bullseye. Zero for everything else. |
|
| |
That'll make your eardrums ache. :) |
|
| |
You might want an outflow of air from the hole. (However, you'd not want it to start before your entry.) |
|
| |
There are no problems with this apart from some. |
|
| |
The main one is that, normally, you would open your
chute at 2000ft, and spend the first 8-10,000ft doing stuff. |
|
| |
If you adopted the same approach for hole-diving (*do not
google that*), you would use only the last 2000ft of freefall
to aim for the hole. I don't reckon you could track more
than a very few hundred feet horizontally in 2000ft of
freefall, which means that the spotter would have to put
you out of the plane pretty accurately. In reality, spotters
tend to put you out wherever they feel like it, as long as
they can see the drop-zone, or recognize a field in the
same county as the drop-zone, or are at least not
offshore. |
|
| |
Therefore, we'd need new technology. The hole-divers
would need to be mounted under the wings on special
racks, and dropped by a military-trained bomber using a
laser sight more or less directly over the hole. |
|
| |
Incidentally, I may consider founding the Barnes-Wallace
Offshore Skydiving Society, if I can refine the release
mechanism and find some sufficiently robust zorbs. |
|
| |
I think if there were not an air outflow from the hole you might stop too abruptly. If the hole were rigged as a tube, the outflow air might be used to power a noise maker or possibly suspend a small child in midair. |
|
| |
So this does not stop you, only slow you down. There would have to be a big mattress, or a pile of feathers, at the bottom of the hole. And then, there you are, alive, sitting on a pile of feathers at the bottom of a very deep hole. How do you get out before the next skydiver comes hurtling down towards you? |
|
| |
You pay the two bucks ..... |
|
| |
// at least not offshore // |
|
| |
That depends rather more on the pilot than the spotter. |

Why not some type of cluster munitions dispenser ? |
|
| |
Glider pilots favour the updraft caused by power station cooling towers; and the shape is such towers is suggestive. Perhaps power station cooling towers could be employed, equipped with suitable blowers arranged around their base ? The pool of rusty, malodorous, lukewarm water in the centre would be a most attractive landing spot...... |
|
| |
I was going to post an idea along these lines; |
|
| |
Make a structure 15'x15' wide by 50' high out of inflatable supports and plastic sheeting with an open roof, but a sealed floor. Set it up in an open field, filling the bottom 15' with water. On top of the water put 5' of alcohol. On top of that, put 30' of xenon. Then drop the skydiver into it with only a 3' drough chute and air mask. They will fall from the plane at ~100mph, then slow dramatically upon hitting the much denser xenon, then the alcohol will ease them into the water, which will slow them all the way to zero. |
|
| |
How do you stop the alcohol and water mixing ? There will be considerable mixing at the boundary unless you segregate them with a membrane. |
|
| |
Xenon is a highly mobile, noble gas. Normal convection will cause it to rapidly disperse. |
|
| |
You could, of course, use Radon ..... |
|
| |
//How do you stop the alcohol and water mixing ? // |
|
| |
Drink the alcohol first, then jump. |
|
| |
//membrane// So it's a single use device, no problem. |
|
| |
Feed the alcohol to the seal. That should make him nice and loose. |
