Thank you very much again for your professional comment, Dave.

advice?

Yes, I agree with you, so Marc please.

at 80,000 feet plus!

Yes, indeed.
If only a Sky 1 had an exhaust at the end of its fuselage, a scramjet
could be an ideal engine, I suppose.
The air could be compressed by the underside of the forward body just
before it would be taken into the trapezoid intake.
And if my memory serves me right, a scramjet does not need turbines,
doesn't it?
The angled wings would make a Sky 1 supersonic waverider just like
the XB-70 Valkyrie.

>> Regarding the nose intake, I would like to consider it is NOT an
intake, but a window for a raser distance measure and reconnaissance.

(pun intended), and would limit the airspeed big time!

I wonder a small flat inclined window makes such a major air
resistance.
For example, the Northrop RF-5 had a flat window at the tip of its
nose, and some variant of SEPECAT Jagur also had such windows.

Anyway, the Messerschmitt Me163B Komet also reminds me of the Sky 1.
Their bodies are both thick and short, and they have same wing-
arrangement, that is, two wings along with one vertical tail unit.
