 The view from the "blown" clear cockpit hood of the Spitfire was considered fair, while upwards good; view to the rear was considered fair for a covered cockpit.The curved plexiglass windscreen however was very bad optically and caused considerable distortion, which made long-distance visual scanning difficult.Spitfire pilot Jeffrey Quill made recommendations for the installation of "optically true" glass into the side panels to solve the problem.
