G.P. Olley wrote in his obituary: "An atmosphere of gloom settled over the war-time base of British Overseas Airways Corporation when the tragic news came through that Captain H. J. Horsey ('Horse' to his friends, and that meant every one) had died suddenly from the injuries he had received in an accident some days before."
Gordon reported that, a few days before, "poor old 'Horse' was concerned that he had broken his clean record - up to then, he had never had a major crash, or harmed a hair of the head of a single passenger."
Herbert is buried in Hatfield Heath, Essex.
