December 4, Lei Xiang and his "big whale" fly up. Map / reporter Li Lin Dong

　　Red Net Zhuzhou December 5 (Xiaoxiang Morning News reporter Qing Quan) airship can not be lowered, the tail is not freely control the direction of the rope entangled in the fuel is being depleted, 46-year-old Lei Xiang Changsha 577 m altitude in the expression and mood unknown. Even so, Ray Cheung or his prior expectations raised 500 m altitude 77 meters, so just a floor, and he could not wait to unfasten their seat belts while clapping, while then another said several "cool."

Yesterday 14:30, Ray Cheung and his four assistants selected in Zhuzhou Road, Hexi Matthey near a four square kilometers, a flat expanse of large aerodromes, in turn spread out he spent a year to complete, and pink and dark blue white airship. Airship length is 26 meters, width 9 m, height of 15 m, the bottom is connected to the engine, flamethrowers and chairs, as well as ensure the airship landing with gasoline and natural gas, is Ray Cheung designed for the high-flying challenge and design. "Before this, I tested three years, the highest flying time is 60 meters." This time he wants to challenge the flight altitude is 500 m, intentions broke the world hot air airship BX-2 category of 458 meters the highest flight record。

　　Airship took off, you need to select the flat, open areas, and to consider in detail the flight weather conditions and the size of the wind direction. "I see a lot of places, it still felt Daping suitable piece of Zhuzhou, and the breeze blowing today, very suitable challenge." Lei Xiang, staring at the driver's seat next flight altimeter and GPS devices, do a final check before departure。

　　Wind pole hanging red ribbon drifting southwest. "Yes northeasterly, the opportunity came." Lei Xiang shouted toward the aide that he got into the driver's seat on the lower end of the airship. He lit a homeopathic inflator, while with his right hand raised high, the machine port immediately ejected by 2 meter long flames, his airship is also accompanied this strong momentum slowly rising. Airship speed of 4 meters per second steady rise in the people's sight lopsided, just hear the roaring sound coming from the airship. Ray Cheung noted flight altimeter, has shown "500" value, hoping to return in accordance with the original route. Do not want to, even though he tried his best trying to debug flame size down, but was an overtopping strong updrafts higher, eventually reach 577 meters in height. Ray Cheung hanging heart and did not lay down, he knows if you continue a delay, the airship will drop sharply because of fuel exhaustion, the consequences could be disastrous. "Fortunately, that kind of airflow passed quickly, I can take the opportunity to decline." During descent, he was rope entangled in the tail because the airship, simply can not control the direction. He later recalled, the airship was "while turning in circles, while declining”。

　　15:10, airship jump in the air for a while "spin ballet", and finally place one kilometer away from the take-off at a construction plant next to a safe landing. Although the flight twists and turns, but it is clear Ray Cheung own this flight greatly exceeded expectations. "In the air, the ground, I feel are so cool, so cool, it finally did not waste a few experiments."

Next, he and his team will focus on the International Astronautical Federation to submit a written application to meet their investigation confirmed that, if approved, will refresh the hot air airship 577 meters BX-2 class world record altitude。
