That is really amazing.

What's with their lumpy runway?

cool vid... awesome runway out in the open, looks serious fun

YouTube description:

According to the pilot-in-command (PIC), he was performing autorotations at the lower part of the main rotor rpm green arc in part due to weight considerations. Upon entering the accident autorotation, he maintained an airspeed between 85-90 knots in the hope that extra speed would allow a more aggressive deceleration flare prior to touchdown, which should in turn further slow the rate of descent and forward speed. The helicopter's rate of descent was high, and as the PIC turned the helicopter onto the runway heading it was apparent to him that the rate of descent was excessive and that he was too low to execute either a proper deceleration flare or perform a power recovery. He attempted to level the helicopter as much as possible prior to impact to minimize the damage to the helicopter and prevent injury. The helicopter landed hard with the left skid contacting the runway first. The left skid collapsed, damaging the outboard landing gear damper attachment structure. The helicopter slid about 100 yards before coming to a stop. According to the manufacturer, the main rotor rpm range is 90 percent to 106.4 percent. At the helicopter's weight and the density altitude on the day of the accident, the main rotor rpm during the autorotation should have been above the 106.4 percent limit (red line), requiring the pilot to increase collective pitch to maintain the rotor rpm within limits. Performing autorotations at the lower part of the green arc provides less availability of rotor energy to perform an autorotation landing. The pilot should have recognized that he was not achieving the required main rotor rpm for the autorotations and terminated the maneuvers. The helicopter was within weight and balance limits.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:

The pilot's failure to maintain adequate main rotor rpm during an autorotation, which resulted in a hard landing.

*quality videography of an aesthetically pleasing aircraft.

As an aside, I find it interesting how deflected the slats (leading-edge control surfaces) were during most of the maneuvres. Not just the looping, but also the rolling maneuvres. They were less deflected for the landing, which took about 20% of the runway length, it seemed.

It was still on the runway though.

This is why you fly with a spotter. This is also why most fields have different areas for Heli's and Airplanes. Watching it I actually think this is the airplane pilots fault. He's calling low pass, but he knows there is a helicopter on the field. Calling low pass doesn't mean that you automatically get to come roaring down the center line. Especially if there is a helicopter, which doesn't and can not clear the runway like an airplane. The heli has just as much right to the airspace as the airplane. And that whirly bird is closer to $500 and the plane is about $2000 with the gear in it. Most likely most of the gear survived (Too bad he hit pavement), Fuji's are built like bricks.

Cargo Plane Taking Off On Formerly Flooded Runway

FTFY.

Fascinating.

For what was this whole thing arranged? They went to pretty extraordinary lengths with all the cameras in the cockpit, on the ground miles before landing, in the traffic control tower, on the runway, etc.

And is the next part of the video really watching them take a boat and to have dinner? I'm so curious.

This was really well done. *promote

What's "not cool" about it? The plane is designed to fly in and out of remote airports with short unpaved runways. It's basically using the propeller as an air brake which allows for a near vertical descent without building up excessive airspeed. Sky diving operators use it because it can make it back to the airport before the sky divers hit the ground and be ready to go up again. Other planes would take several minutes to safely descend from high altitudes, using more fuel and time.

Landing at HK is never easy... and yes, only the most experienced should be allowed to fly in and land there. The way the runway was aligned along with the distance from the airport to the main city... it's mind-boggling for me. But of course, this probably can pale in comparison to other insane airports out there.

Maybe someone out there knows it... but I'm wondering about this: for landing there, is there any flight path that takes you straight in, rather than turning almost 180 on the approach?

All that time in what is to them essentially a 6x9 cell, they finally get let out, only to bite down on a bunch of polyester and nylon. The least they could do is drag a gazelle haunch down the runway for them!
