This guy in the Netherlands Phantom 2 brought to a height of up to 3.4 km.You will have to translate the page to english, This is just nuts.
What do you guys think?

I don't know what that means, I copied it from the article. Very high.

I've been looking at 5,000 ft videos enlighten of the recent issue with a near miss with a drone and jetliner. This video doesn't look any different than those 5k video shots. Most of those video ended with the drone battery life empty and crashing, thats at 5,000ft. I could be wrong but who knows.

"Idioot brengt hobbydrone tot hoogte van 3,4 km"

I don't think there is much doubt what that headline was saying.

Is there any evidence that he went to 3.4km?
I didn't see anything when I skimmed the video.

The problem with taking a P2 to 3.4km is that it would take 11.3 minutes to get up there ...
... and 28.3 minutes to come back to earth making a total of 39.6 minutes.
3.4 Km up and return isn't possible with a stock P2
Carrying extra batteries to give 40 minutes flight time is probably going to be too heavy to get up there.
So .. did he really go to 3.4km and if so ... how?

You are right, the evidence does not stack up.

@labroides - one thign some people do when they go high up - is turn the motors off to let it "fall" to the ground from a high distance - then as it is approaching say 200m from the ground - turn the motors back on for a 'soft' landing. Not smart - but it is what some people do.

Not a smart thing to do, but as long as you can still see what is going on it might work. However he was using a P2, and I wonder if the P2 does not have a limit on the descent speed like the P3 has, so you could come down rather quickly if you are prepared to risk VRS. If you watch the clip, he does descend quite quickly.

I dont understand why flying over 400 feet. Phantom are made for video and photos. Nothing is interesting to video or photo over 400 feet. The best videos and pictures we see on the web from the pro are rarely done more than 100 feet. Flying over 400 feet is extremely dangerous for air plane accidents. How would you feel if because of your drone flying too high and too far away from your ling of sight kill 300 passengers?

Strange, but the maximum ascent speed of the P2 is 6m/sec.  In 3:30 minutes it would reach 1260m  (4134 ft.)  In order to reach 3.4km it would need to be ascending at 16m/sec.  Looking at the cars, it doesn't look like the video's speeded up either & there are no breaks in the video.

I call BS on this one.

I think he actually did make it that high.

Look closely at the edges of the video,  more and more territory/sea becomes visible as time goes by.

He makes it a little difficult by constantly changing the field of view, but I think he actually did get that high.

On the descent, he obviously speeded up the video, as there are some cars moving ridiculously fast.

The P2 has a descend rate of 2 m/s. If you want it to descend faster with some control, switch to manual or maybe ATTI mode. I  don't know what the difference is but I can certainly land my P2 in ATTI mode faster than my P3 Pro. And I never crashed landed my P2 as a result of landing too fast. Talking about my P2 with GoPro, not sure about my P2V+.

Looks like 11,000 to me. I'm a licensed skydiver and we generally exit at around 13,500.  My drop zone is right next to the city of Middletown,Ohio so we do free fall over an area similar to the OPs video . Looks about right to me as far as what I see at 11,000.

It could go down with idle engines and than slow down. I did not try it with Phantom, but with my training quadcopter I practice fast emergency descent and landing.

He means the camera's angle of view, which he's demonstrated.  I agree 100%.  There's no possible way to judge distance without knowing the field of view of the lens & doing some calculations.

As I mentioned earlier though, it doesn't have anywhere near the amount of time required to ascend to that height.

It's not possible to compare distances as seen by human eyes to those of a camera.  There are far too many variables to make it meaningful.  As a skydiver, I expect you can calculate how long it would take to ascend to 11,000ft.  Work it out from the P2 spec & see how it compares to the video.

LOS ANGELES (AP) - A drone came within 200 feet of hitting a Lufthansa jet near Los Angeles International Airport on Friday. The pilot of a Lufthansa A380 approaching the airport on a flight from Frankfurt, Germany, reported that a drone passed about overhead around 1:30 p.m., as the plane was flying at 5,000 feet and was about 14 miles east of the airport, over the heavily populated suburbs of Los Angeles. It landed safely.

That would be way to hard to calculate given the fact that many different type of aircraft are used and many different numbers of skydivers are on a load. If you take a Cessna 208 Caravan (turbo prop ) with 12 skydivers , it might take about 15 min to get to 13,500. That could vary depending on the pilot might take a wide climb as to stay out of traffic, he might have a hangover, all kinds of variables . The phantom on the other hand is going straight up but a loaded Caravan has a bit of a gradual climb and the winds aloft can make the ascent labor intensive on the aircraft. When skydiving with a group, I don't have the time to sight see as I'm busy doing relative work in the dive.  When I do solo skydives I have 60 seconds to take it all in, do a slow 360 and enjoy. The drone video , at 11,000 looks about like what I see at that altitude. My fall rate is about 115 MPH stable. So, what altitude does everybody think the Phantom actually achieved ?

You also overstate the risk to a large passenger aircraft
Have you ever seen what happens to bird weighing several kilos that hit's a large aircraft. Usually the result is: Aircraft:1 Bird:nil.
Most dangerous situations of this type occur when a large aircraft  hits a flock of birds (vis a vis Hudson river incident). I saw this once, with a B737 on take-off, it was an impressive sight with large flames coming out of the starboard engine. The aircraft completed a circuit and landed safely with zero injury/loss of (human) life.
To the best of my knowledge there has never been an incident where a consumer drone has actually hit an aircraft (commercial or otherwise). This despite the millions of drones thought to be out there.

What I have seen on videos in the past, If the drone has great connectivity to the radio, on the way up,
he could possibly cut the motors and free fall back, for a good distance, and eventually restart the motors for a comfortable safe landing. ;-)

Faster descent, and longer battery life...  Just pray it remains upright, for the free fall. Best Flip it out of ATTI. Hahaha

unfortunately it would be like running into a Big..ball bearing at cruising speeds....Not a good result!

Note the specs for the P2V the reported "idiot" used...
At a maximum Ascent speed of 6 m/s it would have taken them 9.45 minutes to reach their 3.4km altitude....certainly doable.....
At a maximum Decscent speed of 2 m/s it would have taken them 28.3 minutes to come down...NOT going to happen unless they had a dual battery set up......and we do not know that......We did not even see the Phantom, a bit of prop etc. but never showed us the real thing....

The P2V battery on a good day would never, ever even come remotely close to that...NOT EVEN CLOSE, maybe 18-20 minutes max in ideal conditions.....Not 37+ minutes...

Not possible without some trickery...unless they had a dual battery (possible) or possibly had a parachute depoloyed after a CSC and they used the find my phantom to get it back...

Yes there are differences between a drone and a bird for sure but what the significance of that difference is still unknown (from an impact consequence perspective) until someone does some proper studies.

Before that you need to assess the likelihood of this happening (risk =likelihood x consequence). Here is a study on precisely that Dourado and Hammond (2016)

So likelihood = rare(very); Consequence = unknown (but likely to be something like major); Risk = low

Edit: this is an engineered explosion in the worst possible part of an engine:
