So basically thing do not have to be in the constitution for them to be constitutional. It's all up to interpretation is what I'm seeing
The basic concept is, anything not specifically prohibited is permitted. The ultra-strict constructionists we have here adhere to a more Stalinist line in that they seem to be saying "anything not specifically permitted, is prohibited'!

That's NOT what the Fouinders intended. They gave us a short document, open to interpretation, so that it could grow with the country.
Thomas Jefferson (on reform of the Virginia Constitution)
Some men look at constitutions with sanctimonious reverence, and deem them like the ark of the Covenant, too sacred to be touched. They ascribe to the men of the preceding age a wisdom more than human, and suppose what they did to be beyond amendment... laws and institutions must go hand in hand with the progress of the human mind... as that becomes more developed, more enlightened, as new discoveries are made, institutions must advance also, to keep pace with the times.... We might as well require a man to wear still the coat which fitted him when a boy as civilized society to remain forever under the regimen of their barbarous ancestors.
Certainly, Jefferson is correct, however there is a line which cannot be crossed.
If the Constitution give Congress the power to provide for all manner of defense as they knew at the time of writing the Constitution, then they did not mean to exclude the Air Force from it simply because it was not specifically named. (In fact, the Air Force was originally part of the Army and could have remained so if it were a Constitutional impediment.
However, when new functions are created out of whole cloth, like The Department of Housing and Urban Development. Then, authority in the Constitution needs to be created for it.
So, progress need not be stifled nor slowed down. But, Congress must have been granted the authority to legislate on items similar. Congress was granted the ability to legislate in interstate commerce, creating port and other transportation needs. Surely, that means they have the ability to legislate concerning airports and air transportation. And the same for space ports and space transportation.
This is not a hard concept to grasp. I suspect people are being very artificial here.
