Just one question...Did X-1 or X-15 ever entered production...?
LOL

No, neither was ever intended to. The He176 wasn't either. The difference is
the X-1 showed the need for an all moving tail at trans- and super sonic speeds
which were used in the F-86 and subsequent successful aircraft. The X-15
provided data for supersonic and high altitude flight. Various production
aircraft used these data as does the space shuttle.

The He176 proved nothing other than a rocket engine could provide enough thrust
to propel an aircraft. This fact was already known. The Me163 not withstanding
there has never been a successful production rocket propelled aircraft. I'd
hardly call the Me163 sucessful.
