Germany's air fleet was grounded this week after "too much biodiesel" fuel found its ways into the gas tanks, according to German reports saying the Luftwaffe cannot safely fly with such a mixture.
Germany's Tornado fleet of war planes was reportedly grounded after an unsafe mixture including too much biodiesel was used to fuel the planes, requiring the fleet to be grounded and their fuel tanks flushed.

"The tolerance values are minimally exceeded," Colonel Kristof Conrath of the Tactical Air Force Squadron 51 was quoted as saying in media reports. "It's not that the aircraft would fall from the sky. For safety reasons, all tanks of the aircraft must be flushed."
Germany is already said to be three months behind in training new Tornado pilots, making the bio-diesel snafu particularly frustrating for the fighting force, these reports said.
