"This officer has now completed a tour of operations comprising thirty-five sorties over enemy territory and involving attacks against a wide variety of well defended targets in France and Germany.
Under a calm and quiet manner he has a fine offensive spirit in action which inspires confidence in not only his crew, but the entire squadron. He has repeatedly displayed ability to make instant decisions in emergency, and his skilful pilotage and good judgement have contributed much to the successful completion of his many operational sorties.
Flight Lieutenant Appleton has been acting in the capacity of Deputy Flight Commander of "A" Flight for a considerable time, where his splendid example and untiring efforts with junior crews has been most praiseworthy."
