Now, remember what I was saying about longitudinal strength of the wing and lack of it in the web/glove?

Now look at the USAF picture

well, I blanked out the non-vertical wing support and look what I get, without the web/glove and with the landing gear door as the leading edge, and the first longitudinal member beside the door (about 1/2 way back the well, and look what I get:

I think you have it. Sure looks like it to me anyway.

sorry for the error:

the landing gear door as the leading edge,

should have been

The alignment of the jagged corners seems to be ahead of the left leading edge and is not being seen from directly below but from about a 45 degree angle. I have compared silhouettes of the shuttles with gear down at approximately the same angle when the undercarraige wheel and door is visible in the same position. I therefore assert that the undercarraige door is down and probably the gear as well. Also, the silhouette of the lower nose indicates the nose doors are open!
Your graphic silhouette looks as if it might be 180 degrees rotated, looked at from above in the fuselage area which I find confusing.
