It can look dumb, but I always had this question as a kid, what physical principles would prevent this?
minus-square@Tarqonlink2•12 hours agoDoes that mean the theoretical speed limit for a jet aircraft is how fast sound propagates through the airframe?
minus-squareDrewlinkfedilink6•11 hours agoNo, a jet aircraft moves by pushing air behind it, the theoretical limit would have to be somehow related to that
minus-square@gruelinkEnglish1•5 hours agoThe theoretical limit could be related to either of those things; it just depends which is lower. (It’s almost certainly the one you mentioned.)

XKCD has alot of thought experiments like this.
