Wow, that's FAST!

Cool.

The SCRAMJet has it issues, the new generation will be a sHcramjet

In a liquid-fuel rocket there is a mix of H2 with O2, so you need 2 tanks (one for each liquid).

But why not collect the O2 from the atmosphere and mix it with the H2 from a tank ?

That´s the origin of the SCRAM Jet...but it´s so complicated that they even call it the SCAM JET...40 years of test and still has problems.

Here it´s some pictures of a sHcramjet:

Is it not true that more than 40 years ago, the XR-71 Blackbird used a form of RamJet technology using a bypass in the engines to reach high mach numbers quite reliably? What problems does the ScramJet have?

I will post the problems of the scramjet soon. You say that the ramjet technology is reliable...that´s ok but don´t make between Ramjet and Scramjet, these are two very different technologies, and the last one is very new so it´s not reliable yet.
