area but faster? Streamlining is still a black art. But it sure is more
comfortable
and feels much more roomy - in the stock Europa I feel like I am driving
a 1957 Porsche Speedster with the top up. I also fly a Mooney M20 (1968) and
even though the width of the cockpits is exactly the same (44 inches with the
cutouts at shoulder height) the Mooney feels claustrophobic. Even the Boss (my
wife) would rather travel in the Europa. In the Mooney she does her co-piloting
