wide. The wing is THIN, maybe a foot? The B17 probably has more
internal space in 1 wing than the SR has total. I had never seen one
on the ground, and I thought they were 1/2 again as large.

Here's a picture of the D-21 at Evergreen (you can just see the nose of the
B-17, which is behind the SR-71 in this photo, the D-21 to the right and in
front of the the SR-71's left wing, and part of the trailing edge of the
right wing of the Spruce Goose at the top of the picture frame):
