One must be impressed and reassured by the determination of the Number One engine to keep on running despite the equivalent of a monsoon deluge administered by the airport fire brigade.
Frank Whittle had a similar problem on 12 April, 1937, when one of his early models on a testbed at Rugby raced out of control and set fire to the rope shed. Workers ran for cover, but FW stayed cool and managed to shut off the fuel supply. That was only 73 years ago.
The Trent engine probably wouldn't even fit into Frank's rope shed.
