3. no dents or deep scratches (just to think that even if you drop a camera or anything into a body of water from a height of 3,000 feet would surely smash the object to pieces especially that he claims the velocity was 110 miles per hour, how much more if it landed on the ground?)
For the record, water is MUCH more dense than a pile of grass and dirt. Falling on water from 3,000 feet is like falling on concrete. If you don't believe me, try a belly flop at the pool, and then do the same thing on a pile of hay or a mound of dirt.

Gee ... I wonder how a 1-series would hold up.

for the nay-sayers...

I dropped my 18-55 from a height of 3 feet, it bounced about 2feet and i caught it. That one hit was enough to torque the focus mechanism to be stuck in MF, and free-spinning in AF. Ergo, there's no way it would survive a 3000ft drop, mud or not

also, mud, like water, effectively turns unto concrete for falling objects. Unless a small earthquake happened at the same time, it's bogus.

I think someone needs to write this one into Mythbusters.

That is awesome. I don't think I'd try that with my 1Ds III, still.

Yea send it in for Mythtbusters Sorry, I don't buy it either.

One would normally say the same about a person falling great distances, and yet there are a few miracles on record regarding skydivers survivng freefalls, while there are also stories of people breaking their necks when tripping while crossing the street. It is unwise to say "no way."

Absolutes...aren't.

Good story. You think they'll use this scenario in future product testing?

Here's another 'take' on the authenticity of this story...Years ago I was an avid sky-diver and our landing zones were dry farm fields that were 'regenerating'. However, we were surrounded by other active fields...some of which were plowed (= loose soil), and overgrown with crops. I always thought that some of these fields were so overgrown that a skydiver with a partially open 'chute falling hard would survive landing in one of these fields. Once, I turned with the wind on my final approach (which meant I was going to land hard)...I ended up drifting over the next field which was as described above and it made for a very effective 'cushion' for my landing. So, I think it's possible that it could have occured as described if the landing site had loose, fine, plowed dirt and tall vegetation. The video camera could have taken an initial impact (on a branch) which destroyed the video but took most of the impact force and then flipped through some softer vegetation (slowing down even further) and finally landing (at a relatively slow speed) in the soft loose soil. Yes, it's a stretch of the imagination and maybe even one-in-a-million but it could have happened. In fact, sky-divers have been known to survive 'chute failures at (near) free-falls speeds because they landed in thick vegetation.

Upon further investigation, it was discovered that the XT was originally registered to Chuck Norris. Therefore, it is true and it did survive the fall.

I think it has to do mainly with the trees combined with the mud. Branches slow down a light object pretty gently, even at very high speeds. I don't think it really makes a different if the camera fell 1000ft or 100ft. Terminal velocity would've been reached in both cases. I do think that you're much better of throwing a DSLR from 1000ft into the mud then from 10ft onto concrete.

I think a rebel could survive a tougher landing, like the video camera clearly had. In that case he lens would be shattered though.

I find it really amusing that people are saying this is fake, stating that you can't jump out of a plane with video and still cameras on your head without breaking your neck... I guess I've just gotten really lucky the last couple thousand times I've done it.

Anyway...

Did the whole carbon fiber plate rip off the helmet or did the quick releases you've got the cameras mounted to fail? (or both?) I always cringe when I see carbon fiber overhanging the sides of the helmet by more than a quarter inch or so. Top-mounting landscape stills and a video camera can be tricky, but an HC40 and a 350D should be able to fit on that helmet with no overhang.

Also, cut the excess off that ring sight post! It's just sticking out there waiting for something to get snagged on it.

Looking at the timing, the camera ripped off at 2:28 which gives it 21 seconds of time before hitting the ground. The system seems to be spinning a lot (up and down, sky and earth alternatively) but still the average speed would be 3000ft*0.305m/ft / 21 s = 43.6 m/s = 157 km/h. Considering that the system was already at free fall when the camera separated, there wasn't really any significant acceleration phase. Thus, I would conclude that the speed that it hit the ground was around that value.

It would be nice to see what the landing area looked like - maybe the camera had hit a tree on its way down?

What makes water fatal is its high surface tension.

It probably did accellerate.

The skydiver would probably not have been falling at terminal velocity. Unless tucked into a ball or diving head- or feet-first, the aerodynamic drag will slow a skydiver's fall considerably, especially if he or she is wearing a wing suit as many do these days.

Maybe the XT had its previous life as a cat
