It is perhaps just worth reflecting on the maximum cleared airspeeds in some of the types mentioned. The Jag with tanks fitted was 0.95M and the Tornado F3 without tanks was 800 KCAS. The reasons for speed limits are usually not promulgated but may be due to the limit of testing, a handling qualities characteristic or a structural consideration, either for ultimate load or fatigue. Please do not take this as a criticism of anyone because I also have knowingly (and unwittingly!) exceeded published speed limits in some aircraft, but it is something that is worth contemplating in the context of this discussion.
My fastest/lowest combination was 700 KIAS at 100 ft overland in a CF-104 out of Cold Lake - and that was spectacular!
