Ah yes, living in Minehead throughout the entire Concorde operational era, I fondly remember those evening "babooms", usually preceded by the clattering calls of startled pheasants (no, not peasants
or dogs) in the woods behind us who seemed to get a second or so advance warning, presumably at a frequency range above mine.
There was also a definite difference in the intensity of those secondary booms between summer and winter, with the latter being slightly louder and more reliable than the summer ones.
What a beautiful sight it was too in a clear blue sky, with that gleaming white shape spearheading the contrails that would gradually knot up and disperse as it headed up the Bristol Channel and disappeared towards Bristol. Twice a day in the evenings and another in the afternoon when the Washington flights were operated.
Happy days, much missed!!
