Has anyone else experienced a shockwave from another aircraft during their career?
Like Wiggy, I too was 'bounced' once by CCDE in a 744. We departed JFK eastbound early one morning (the return sector of the 'daylight maniac') and watched the BA2(?) boarding as we taxied out. Sometime between Boston and Halifax, we felt a similar 'double knock'. As the conditions were otherwise serene, we immediately suspected the white pointy thing. Sure enough, there she was, overtaking us and a good 10,000ft higher.
Interesting to note that we flew backwards through the shockwaves!
