First plane I ever flew in was a S-2 Tracker at NAS Glenview in 1966. My buddy and I hitched a ride one night with a reserve pilot and co-pilot while they flew GCA's at Midway Airport. The flight was about 1.5 hrs and downtown Chicago was beautiful. When we got back we still heard the roar of the R-1820 engines in our ears long after we left the flight line. Not a lot of sound-proofing in a Stoof. :d
