Yes, or to be more precise, the Westland-Hill Pterodactyls, and the program was killed off.
The program wasn't killed by the Air Ministry, they were providing specifications and buying prototypes.
He did indeed.
There was a bit of nepotism going on at Westlands, Sir Ernest Petter, Teddy's father appointed him to the board as technical director over much more senior and experienced engineers, which ruffled a few feathers including Geoffrey Hill. One of Teddy's first decisions as technical director was to cancel the Pterodactyl program, which had the Pterodactyl VI in development as a front turreted fighter version of the rear turreted MkV, wind tunnel models of a 4 engined seaplane MKVII were being tested, and a proposal for a transatlantic airliner MkVIII was being worked on.
