トルネードの燃料にバイオディーゼル混ぜすぎて安全の為に、タンクを洗浄する必要があるって
ちょっと酷すぎませんかね

It gets worse. According to local media, the fuel used by the German Tornado fleet appears to have been mixed with ‘too much bio-diesel’. According to news site Frankfurter Allgemeine, this was noticed during a routine check last Monday:

“The tolerance values ​​are minimally exceeded,” said Colonel Kristof Conrath of the Tactical Air Force Squadron 51. “It’s not that the aircraft would fall from the sky. For safety reasons, all tanks of the aircraft must be flushed.”
