Can Velocity or Cozy fly at/above 25,000 feet with Superior
supercharged 360 engine? A friend of mine is considering to fly a
Velocity or Cozy for long and high trips and would like to know their
capacity for this kind of mission. I personally haven't heard any
Velocity or Cozy flys at this altitude regularly. But my friend wants
to give a try. Any thoughts, especially some caculation to prove?

Thanks a lot.
