Everybody does , i guess the human curiousity is to blame

It was a well controlled hard landing in an open field
the rotor blades were intact though the tail was totally damaged
even when the engine loses power, the rotor can still generate certain uplifting force which lessens the impact of the hard landing
no explosion or any obvious fuel or toxic gas leaks due to the special sealing and anti crash design
the weight of the engine has caused the roof to collapse
The body caved in and the landing gears were all broken to absorb the force of hard impact. These are all credited to the functioning of the anti crash design

Here an article extract describing the landing gear can absorb a hard landing of 10 tons

第二，直-20拥有实用的特殊构型。
该机采用了不可收的后三点式起落架。不可收的好处是在直升机突然坠落时有更强的安全性，这说明直-20在设计考虑上更重视直升机的抗坠毁和成员的存活率。后三点式起落架的好处是，在粗暴着陆时，尾轮首先触地而消除了直升机的惯性，不需要在较高的抬头姿态飞行时保护机体的尾撑或其他相关装置，从而大大减少了后机身的载荷和重量。

从实用化的角度看，尾轮的突出优点是在贴地飞行时可用作“探头”，这样，飞行员就更有信心进行超低空飞行，而不必担心直升机触地引起机体的重大损失。当直升机进行地面搬运时，后起落架与主起落架间隔距离较大，直升机更加稳定，不容易向后翻倒。这一优点在野外不平的地面上显得更为突出。直-20的起落架还有双腔式吸能装置，能使直升机以很高的下降速度着陆，并能承受近10吨的冲击载荷。

.....

直-20的油箱是抗坠毁油箱，油箱位于座舱后部，并留有内部辅助油箱、外挂辅助油箱和空中加油的管路以及接口，以进一步增大直升机的航程。



2. the Z -20 has a special structural design

The machine uses a three-point landing gear. Not received the benefits of a sudden there is more security when a helicopter crashed, indicating that the survival rate of the helicopter straight -20 more attention to anti-crash and members of the design considerations. Benefits tailwheel landing gear is in the rough landing, the tail wheel first touchdown while eliminating the inertia of the helicopter, do not need to protect the body of the tail brace or other device while flying high nose-up attitude, thus greatly reducing the post-load and body weight.

From the practical point of view, highlighting the advantages of the tail wheel is affixed to the ground when used as a "probe" so that pilots would be more confident in low altitude flight, without having to worry about the helicopter hit the ground causing a significant loss of the body. When the helicopter ground handling, landing gear and main landing gear after the interval greater distance, the helicopter more stable, not easily tip over backwards. The advantage of uneven ground on the field becomes more prominent. There are twin-gear straight -20 energy absorption devices, enabling the helicopter landing at a high rate of decline, nearly 10 tons and can withstand shock loads.

.... Z-20 isequpped with a crash resistant fuel tank, fuel tank located in the rear cockpit, and left internal auxiliary fuel tanks, external auxiliary fuel tanks and piping as well as aerial refueling interface to further increase the helicopter's flight.

Helicopter crashing without the sealing technology will be like this such as black hawk:

Cant say because they may not be dropping from the same height

When a helicopter lost its tail rotors, it will spin but the main rotor will still provide sufficient gyro power to slow down the descend. The worse fear is spinning out of control and crash head down or smash sideway, thus if the pilot can ontrol the descending with managable spinning hhis chances of surviving will be good.

Skill of pilot and heavy built hull plus excellent fueal leakage sealing design as well as combustion property of fuel all play their roles.

The pilot reported an explosion at the tail before crash, photo showed there are power lines and cable towers nearby, so may be the tail hit the power line or tower which cause the lost of tail rotors.
