Bill Waterton (Javelin test pilot) said in his book, ‘The Quick and the Dead’, that he had outmanoeuvered the 110 in mock combat at 35000ft.
He was also pretty scathing about the Javelin’s controls and Glosters in general.
One RAF instructor I met sighed wistfully and said ‘to think that we could have had 110s’
Another chap I met said that it couldn’t be flown in cloud as the engines went out! Just the thing for an all-weather fighter. Never seen this mentioned anywhere else though.
