That is really cool, thanks!
I now understand why the 51's intake duct was dropped below the surface of the bottom of the fuselage.
Strangely enough, it fits into some of the knowledge I picked around the car racing industry.
I think if you want to see some of the most intensly developed aerodynamics in the world today, you can find it in Formula 1 racing. Those guys a constantly reworking their aero packages as the rules and conditions change.

A pig is a pal, who'll boost your morale, Though mountains may topple and tilt.
When they've blackballed, bamboozled, and burned you, When they've turned on you, Tory and Whig,
Though you may be thrown over by Tabby and Rover, You'll never go wrong with a pig, a pig,
You'll never go wrong with a pig!" -- Thomas Pynchon, "Gravity's Rainbow"
