You can't fly helicopter's, they beat the air into submission. Besides, everyone I have ridden in vibrated and was noisy. I rode a Sikorsky S58 on a cargo run from LAX to Long Beach Ca one time. When he lifted off witht the load I thought every radio and instrument was going to vibrate out of the panel.
