Doesn't paint a good future for large scale aeronautics on Mars - even if you somehow can sustain those speeds in an atmosphere where you cant burn stuff for propulsion, landing the thing, somehow, at the destination would be very hard - possibly harder than landing the F-104 Starfighter!;-) That speed likely rules out any normal landing gear or runways, possibly with the exception of a maglev catcher cradle. Most likely the "aircraft" would need some sort of a robust long duration vertical landing capability, likely rocket based. No wonder you don't see any aircraft on Mars in The Expanse series - only hyperloop like pods on flimsy rails making use of both the low pressure and low gravity or full on spaceships or orbital shuttles.
