Working construction at Atlanic Canada airports for six years I saw many types of aircraft up close and personal and two experiences are far above all others. Both in Goose Bay, Labrador on one job. We were doing routine checks on the landing aids on the sides and approaches of runways while squadrons of jump jets were taking off (4 at a time) and landing. Vibrate your entire body. During one break, my boss took me up a hill until we reached a fence signed "Armed patrols beyond this point". He said I was gonna love it and he was right as we watched Vulcans touch-and-go, come almost at us and turn very close to us for another T&G. Awesome piece a gear! I was amazed at how slow they were flying and how big they are.
