1930, aged 22

b. 7 April 1908, in Lambeth, London

As you can see, he was over 6ft 4in in height. Despite this, learnt to fly in Kent, got his aviator's certificate in 1930 and then became an instructor at Brooklands in Surrey.

Pilot, with Owen Cathcart Jones, of one of the D.H. Comets for the MacRobertson Race in 1934; given third prize (erroneously, in my view, but it's probably a bit late to say that now).

In 1935, got annoyed with Owen Cathcart Jones for something he said in his book that Ken felt "reflected on his courage and ability as a pilot", and even went to court over it. Owen replied that "that was the last thing he intended, as Mr. Waller and he had been, and still were, very good friends", which seemed to settle the matter.

He and Max Findlay competed in the Schlesinger Race to South Africa in 1936, in an Airspeed Envoy (No 13), but this crashed on take-off in Northern Rhodesia, killing Findlay and the radio operator; Ken was thrown out through a hole in the fuselage and badly hurt.

After WWII, became Miles Aircraft's chief test pilot (he delivered a Hillman Minx car to Orkney in 1948 at a cost of £35, you may remember).
