NASA aircraft thrill aviation buffs in Southern Taiwan

NASA aircraft thrill aviation buffs in Southern Taiwan

2024-03-13

NASA sent two research aircraft over the skies of Taiwan on Wednesday, as part of an Asia air quality study. One aircraft the DC-8 dropped to just 15 meters above ground when flying over Tainan and Chiayi. The sight was a thrill for aviation fans, who flocked to the south to take photos. One ardent fan even took the high-speed rail from Hsinchu to capture the event.

I came down this morning from Hsinchu on the high-speed rail, and then I rented a scooter. This is such a rare event, and the aircraft flew at quite a low altitude. It was really something.

Because the aircraft is so old, its condition is problematic. That’s why two of its flights were canceled previously. Today was its last flight before decommissioning. It had to be near the airport before it could drop its altitude. Right next to the airport, it could drop to a lower altitude to take very clear pictures. The plane is equipped with precise instruments that require low altitudes to take accurate measurements. When it’s flying high, the air quality measurements are completely different from those taken on the ground.

NASA’s DC-8 research aircraft flew between Tainan and Pingtung on Wednesday, measuring changes in air quality. Its data will be used to study the effects of atmospheric circulation, pollutants, and topography on air quality. Also on Wednesday, NASA’s second aircraft, the G-III, flew at a higher altitude over southwestern Taiwan.

NASA兩架科研機來台! 低空飛西南部上空 航空迷搶拍

2024-03-13

環境部跟美國太空總署合作七海計畫高屏3D空品實驗,NASA科研機DC-8及G-III都經過台灣,其中低空飛行任務的DC-8,飛越台南跟嘉義時,降到大約15公尺高度,讓航空迷們能拍個過癮,甚至有人特地從新竹南下拍攝。

“從新竹早上坐高鐵,然後來這邊再租個摩托車,很少見,還蠻近的,而且飛蠻低的,就剛好他飛得低,就還不錯這樣子”

[[國防安全研究院 副研究員 舒孝煌]]
“因為它這架飛機很老,他機務的狀況其實有問題,所以他前面已經取消了兩次,今天這是最後一趟,飛完之後它就會除役。它的航線要接近機場它才能夠降低高度,你在機場旁邊的話,就比較低的高度就能夠拍到非常清楚的畫面,飛機上面有比較精密的儀器,要在比較低的高度才能夠進行偵測,如果飛很高的話,空氣品質跟地面上是完全不同的”

這部飛機,就是科研機DC-8,透過貼近地面的飛行,量測空氣汙染物變化,以了解大氣環流、汙染源及地形等對空氣品質的影響。而另外一架G-III飛行高度約2800英尺高度,所以無法像DC-8拍攝的這麼清晰。
