What Norman Macmillan's fog flight revealed about the Flycatcher

Keeping the same test pilot and chief designer throughout an aircraft-development program makes recurring defects easier to recognize. When that is impossible, test pilots must document and share their impressions clearly; Eric "Winkle" Brown is cited as a model of reflective judgment. Norman Macmillan then flew a Flycatcher into dense fog because official acceptance still required the aircraft to leave the ground. Without radio or useful blind-flying instruments, he completed a short climbing turn and landed after only two minutes. He credited the reasonable outcome to well-coordinated controls, stability in every axis, and the pilot's position near the center of gravity. The account connects the Flycatcher's forgiving handling with the disciplined observation needed to develop aircraft safely.
