Airborne Artiste'
Living near a secret Cambs. Tutor base we live with the noise levels under the climb out from W***n. However as a clapped-out' old ex AEF Pilot concur completely with your view on getting the next generation airborne. But, why are they noisy? Prop. tips going supersonic as per Harvard or is there a hole in the exhaust which ATS could fix? Could some of our TP brethren explain why?
