Personally, I want to know where to hire a Cessna like this one
that the guy with the first feedback got to fly once........
This may well mean that the small aircraft are not able to operate efficiently and are subject to significant ATC delays. But with a 747 burning 12500 litres per hour, and a cessna burning about 300 LPH, I believe its more important to have the commercial aviation running as efficiently as possible.
Perhaps he may find GA even more efficient if he puts the drain plugs back into his fuel tanks?
