But I also have zero doubt there is airborne tech far beyond anything that is public knowledge. The SR-71 was developed in the 60's. The X-43 was developed in the early 2000's (and was useless except for breaking the speed record). There have been no significant record breaking advancements or major shifts in tech since.

We've gone from shity computers, brick cell phones and single use rocket boosters to pocket sized super computers and vertical self landing rockets since. You bet they have developed some crazy, outside the box flying machines we don't know about.
