Can you survive freefall into water

Jointly US-Dutch owned Booking. The alleged miscreant, named as "Andrew", is said to have stolen "details of thousands of hotel reservations in countries in the Middle East," according to a new book written by three Dutch journalists. Helpfully for non-Francophones, the homepage and much of the info is in English — although saying that, just to warn you, the same isn't true of all the background information and the various organisational pages we're about to link to.

Hewlett Packard Enterprise has bagged a contract to build a supercomputer for the United Weather Centres — West, the remit being to help improve the accuracy of forecasts in Northern Europe. While the current version, Version 8. We've done a lot of joint work. Microsoft has contributed to the Linux kernel in support of better performance. SQL Server runs very well on Linux and our customers see a lot of value in having the combination. What is a system role?

UK-based price comparision and broadband swapping service Uswitch has totted up the figures and come up with a surprising candidate for most outage incidents in Outages are a tricky thing to quantify, and the metric used by Uswitch was a simple count of the most visited websites against a total number of incidents reported by DownDetector.

The "visited website" metric ruled out the likes of Azure and AWS, although both services lurk behind the scenes. However, hotspots like Facebook, Instagram, and TikTok all qualified.

At incidents, according to Uswitch, Reddit was head and shoulders ahead of the pack. A whopping 60 per cent of issues were related to forum's app.

Following, at incidents, was Discord server connection woes afflicted 73 per cent of blackouts , just snatching second place from Instagram. The food and lifestyle happy snapper accounted for incidents the app accounted for 55 per cent of problems. The Register - Independent news and views for the tech community.

Active 2 years, 10 months ago. Viewed k times. I'm assuming the damage caused will be mainly due to amount of force and not the duration Assume you jump head first and hold a sharp and strong long object that cuts the water before you arrive, will that make the entrance to the water more smooth and protect you?

As it stands the answers have no physics in them, which is not a good sign. It is evident that no matter how much one tries to model the human body and behavior the data are necessary to set the scale. Here is an attempt: en. I'm looking for a numerical answer which will demonstrate the differences in force experienced in each type of fall, out of considerations of impulse and the density of matter you fall into.

It is less important to me how many newtons are required to smash a bone. Add a comment. Active Oldest Votes. Assuming you are doing the right thing, and optimizing your form for water entry, you will simultaneously be minimizing your wind resistance during the fall: 1. Improve this answer.

When the brain don't get enough oxygen, the heart beat become slow and the person may suffer nitrogen narcosis and forget to breath..

In spite of my last line about drowning, I think you could possibly survive intact if you hit a large wave just right. If you are tucked you are less likely to be injured as you are already "folded up". Water is extremely hard without some air in it, and although you will be at maximum speed as you hit the surface, that surface, given the right conditions, maybe the softest portion of what you'll hit, whereas if it is flat calm it will certainly be the hardest.

I'd honestly say the odds of surviving a fall from 7 kilometers would be 0 Hitting water at KPH would force your legs up through your body and kill you on impact if you hit feet first the impact would shatter not only bones but cause massive internal bleeding, i doubt you be alive to drown.

Even assuming a minimum terminal velocity of 60 mph, and being able to change to a vertical position with your legs crossed and entering the water feet first reducing the impact decelleration your death will result from the massive trauma to legs, spine, neck and internal dislocations. If you were un lucky enough to survive you would need critical care immediately to live more than a few minutes. Concussion, spinal compression fractures, torn internal tissues and numerous broken bones would be the minimum damage from such a fall.

When falling you want to present the greatest cross-section possible to increase drag and minimize terminal velocity. When hitting the water you want to minimize the cross section to minimize deceleration injuries they say it's not the fall that kills you, it's the sudden stop at the end. Normally, I'd dive head first with my hands in front, but at that speed I'd be afraid I might break my neck. So instead, I'd go feet first, with the feet in tip-toe position, and the legs crossed and tense to minimize the chance of my feet separating doing the splits at terminal velocity would not be fun.

I wonder how deep in the water you'd go? I've heard of one way of getting rid of people that some governments have done, is dump them from an airplane into a swamp. No funeral necessary. Does anyone really think it really matters what position you are in when you hit? However, in WW2 a bomber crew man jumped out of his bomber and fell from about 18, feet, he lived but he fell through a pine forest and very deep snow and slide down a hill, what are the odds of that happening again!

You may also want to spread out after penetration so to slow your speed and hence your depth which you'll have to swim up from. But this is seriously highly hypothetical and mostly inapplicable by even the best divers. You may just wanna do some stunts in the air, enjoy the scenery, and aim at land if possible :-D. World Record Highest Dive. I think the best shape might be a cross; a star of David; or some such symbol depending on your personal beliefs.

Incidentally, does anyone have any strong evidence about how soon you would die for a head first dive or a belly flop? I think it would be slightly quicker head first, because you would hit the water faster and crush your skull to mush over a shorter interval.

On the other hand I can see that the massive organ damage caused by landing flat would see you out of this world and into the Darwin awards pretty quickly too. I think the belly flopper is going to kill you quicker.

You get to crush your head if it crushes at that speed , but if not, I expect the temporarily increased blood pressure will burst all your arteries. In any case, a belly flopper hurts even at swimming pool distance falls.

A "belly flop" at 60 mph is likely to split the skin open and leave you a mass of jelly with some manner of attachment to the bones maybe. This episode shows his technique unfortunately it cuts off just before he detaches The guy in the video hurt his hands a bit I think, didn't seem like he had time to properly position them before impact.

Nonetheless, nice jump. I wouldn't do it. I've jumped from decent heights of about 10m or so some time ago, and I also noticed that once going down legs first I was also able to bend them outwards and so make a partial loop in the water whereby at the end of the dive my legs would be pointing upwards towards the surface and head would be pointing down, this way I prevented myself from going any deeper than I should be had I maintained straight position and I'm wondering if the same trick would work for high-alt jumps.

AND he actually pulled it off, all the acrobatics then a perfect hit, you can't do that without serious calculations and immense training and When there are 5 judges, the highest and lowest scores are thrown out, so he ended up with those three 9s and that second judge didn't affect his score. But you can see the middle judge looking back at the second judge's score like, "WTF?! All I'm saying is that if I had done that and got that score it wouldn't just have been the score that got thrown.

Yeah, there's something going on there. Everybody there knew that was an awesome dive except that second judge. I don't know what he thinks he saw but there is no way that dive deserved a 7.
