Hi cougar.

Go to the aircraft.cfg file in FSX\SimObjects\Airplanes\CS_B707-300 and change the eyepoint setting, under [views], like this:

[Views]
eyepoint=55.0, -1.6, 5.8  //55.0, -1.6, 5.55

The red text is the original setting.

I found that raising it to 5.8 did the trick for me, but you might prefer a slightly different height.
NOTE: If you were to change it from 5.55 to 6.55 your view would be 1 foot higher.
