    > 5. At some exact airspeed you lift off the runway.
    > 6. Gear up
    > 7. Milk up the flaps and fly.
    > 8. Leave the power at 100%
    >
    > Flying the jet
    > 1. &nb sp; Climb at 100%
    > 2. Cruise at 100%
    > 3. It is silent in the plane.
    > 4. You can't see clouds because you are so far above them.
    > 5. You look down and see lightning in some clouds below and
    > pity some poor fool that may have to fly through that mess.
    > 6. The jet plane is air conditioned!! Round engines are
    > definitely not. Jet engines are not round? If you fly in
    > tropical areas, this cannot be stressed enough.
    > 7. There is not much to do in a jet, so you eat your flight
    > lunch at your leisure.
    > 8. Few gauges to look at and no levers to adjust. This
    > leaves you doodling on your knee board.
    > 9. Some call girl friends on their cell phones: "Guess
    > where I am etc"
    >
    > Some observed differences in round engines and jets
    > 1. To be a real pilot you have to fly a tail dragger for an
    > absolute minimum of 500 hours.
    >
    > 2. Large round engines smell of gasoline (115/145), rich
    > oil, hydraulic fluid, man sweat and are not air-conditioned.
    >
    > 3. Engine failure to the jet pilot means something is wrong
    > with his air conditioner.
    >
    > 4. When you take off in a jet there is no noise in the
    > cockpit. (This does not create a macho feeling of doing
    > something manly)
    >
    > 5. Landing a jet just requires a certain airspeed and
    > altitude---at which you cut the power and drop like a rock to
    > the runway. Landing a round engine tail dragger requires
    > finesse, prayer, body English, pumping of rudder pedals and a
    > lot of nerve.
    >
    > 6. After landing, a jet just goes straight down the runway.
    >
    > 7. A radial tail dragger is like a wild mustang---it might
    > decide to go anywhere. Gusting winds help this behavior a
    > lot.
    > 8. You cannot fill your Zippo lighte r with jet fuel.
    >
    > 9. Starting a jet is like turning on a light switch---a
    > little click and it is on.
    >
    > 10. Starting a round engine is an artistic endeavor requiring
    > prayer (curse words) and sometimes meditation.
    >
    > 11. Jet engines don't break, spill oil or catch on fire very
    > often which leads to boredom and complacency.
    >
    > 12. The round engine may blow an oil seal ring, burst into
    > flame, splutter for no apparent reason or just quit. This
    > results in heightened pilot awareness at all times.
    >
    > 13. Jets smell like a kerosene lantern at a scout camp out.
    >
    > 14. Round engines smell like God intended engines to smell and
    > the tail dragger is the way God intended for man to fly.
    >
    > 16. Round engines have a tendency to make strange noises,
    > especially at night over water.
    > Pass this on to real pilots.
