The quite loud "bang bang" windowrattling crack of a supersonic pass - mostly high level ones -was quite characteristic. Almost never heard today. (Except when an F-something get too involved in a dogfight, and the tropopause is not as predicted.
) But there was the Meteor "blue note"! It certainly stopped you in your tracks. They seemed to go pretty "high speed", but were probably slowing for landing (and in idle?). (I lived for 20 years 3 NM North of Karup, EKKA). The Hunter had something similar, but not so "deep". Hunter example: Two Hunters on "rat patrol" catching four G-91's and "gunning" them: Strange deep howl from the Avons' slowing to the Fiats' full out speed.
In 25 years daily listening to Drakens I heard the same thing only a handful of times. (It had an Avon 200 engine). But the Meteor was something else - though hopefully never "near" supersonic. It would have been fatal. (Danish total losses
pr. 10.000 flying hours: Meteor 4 - 9.13. F-16 - 0.45. Meteor 7's unknown, but 7 lost of 9. One scrapped, one preserved. Seven crashed. First loss after 4 months pulling the wings off in a high speed pull up.
