飛機緊急迫降 竟是牛群放屁過熱
Apr 7th 2014, 18:38

英國民航處的數據顯示,當地機場過去兩年收到1,262次求救訊號,當中186次是遇險求救信號,其餘都不太緊急,從撞上雀鳥到機組人員病倒都有。其中一次飛機需緊急降落的原因,竟然是機上運載的牛隻過熱,觸動火災警報。

該架波音747航班,途經愛爾蘭海期間,火災警報突然響起,需緊急降落希斯洛機場。飛機降落後,技術人員檢查飛機,但未有發現起火,推測可能是所載的390隻牛隻產生大量熱能,觸動警報。

牛的平均體溫為攝氏38.6度,稍高於人類體溫,而且因為腸胃氣脹,每日會釋放100至200公升甲烷。因此,當多隻牛聚在一起,釋放氣體並散發體溫,機上的溫度可能會上升,觸發警報。(國際中心/綜合外電報導)
