I do not know the reason, but every delta winged aircraft that I can recall
ever having seen pictured has had a pronounced nose high attitude while at
rest.

From that observation, it is easy to infer reasons--and, of course, to be
wrong!

If anyone here actually knows the real reason, please post it. (Inquiring
minds want to know.)
