B747 Ground Contact Angles

I still can't picture how you can get a strike on an inboard engine.
With Flap 30 degrees, Gear Struts Compressed and assuming the Roll is about the outside tyre of the Wing Gear, at a typical pitch attitude on touchdown of approx 5 degrees Nose Up the inboard nacelle will contact the ground at a little less than 7 degrees roll angle (PW & GE engines) about 1/2 degree less for Rolls Royce Engines. Higher the pitch attitude on touchdown the lower the roll angle required for ground contact.

It's surprisingly easy to get there in challenging conditions.

I would have attached the chart but my posting skills fell short of inserting a jpeg image. If anyone can let me know how to do it I'll insert the chart.
