Has anyone else experienced a shockwave from another aircraft during their career?
A few times in my military days, but as far as civilian career and Concorde encounters just the one: We (744) were heading westbound on an Atlantic Track, a Concorde coming the other way and broadcasting the fact on air to air - we were on an 180 X 0 with lots of delta h

. We saw it go over the top and the shockwaves manifested themselves as a fairly quiet double "knock" ..TBH I'm not sure we'd have noticed if it hadn't been for the heads up on the R/T...we certainly did not get a "loud bang".
FWIW the most impressive thing I remember about the encounter is having a peek up with the weather radar (old habits die hard) and seeing a return the size of a barn door well outside 20 miles ...stating the obvious but those intakes sure as heck weren't designed with stealth in mind.
