The only issue I have at present, and I am only going to state it for the record, but will not hold up the submission.
1) I am presuming that the scram jets are the ones attached to the 'wings' in the artwork. The artwork does not conform to the definition of a scramjet. A scramjet is an air-breathing engine, but from the imagethe front of the engines is enclosed, and that means no air can be forced into it and compressed to scram....
So unless anyone else has any more major issues, I will approve this tomorrow.
