I've actually had the pleasure of flying the CV990 Coronado. Unfortuneatly I was only 1 year old, but according to my dad it did CPH-MAD in less than 3 hours. Probably had some favourable tailwinds, but that's still around 30 - 45 mins. less than a current day MD80 with SAS or Iberia.
The best part though, unless you're a treehugger, was the smoketrail it left on take-off. Rumours has it that a clever ATCO fellow actually issued a RVR on the ATIS after a Coronado had taken off
It even made a Phantom bluss from embarresment !
