It's actually kinda begging the question to presume that any natural selection did have a target without demonstrating one...
If evolution is blind, then shouldn't cumulative selection be demonstrable without a target? This is a fair question.

Yes and no: yes, there are certain ideal traits that reoccur, no they do not constitute a "target" that is being shot for. You're still approaching this backwards: rather than being the end goal, these traits just bear out to be the most useful in a set of given circumstances, and so those mutations that lead to them get favored.
The answer can't be yes and no because that is contradictory. Either evolution homes in on some set of targets as guided by the fitness paradigm, or it doesn't. The answer is yes it does.
Now you're basically claiming these targets don't exist until evolution produces them and therefore I am looking at it "ass backwards". This isn't true because these targets exist as possibilities or potential outcomes. Maybe it would be clearer if the question were phrased:
Do you agree that for any selection criterion, there will exist some set of potential outcomes which evolution will home in on?

OK - do you think the person that came up with the wheel had a Ferrari in mind as an end-point - or even a midpoint?
Do you think the Wright brothers considered the 747 as they made their flight?
When the Germans made the V1 and V2 rockets were they thinking of the moon or Mars as possible destinations?
How many do you want?
You listed the 747 as a target for the cumulative selection of manned flight, the Ferrari as a target for the cumulative selection of wheeled transportation, and the moon landing as a target for the cumulative selection of rocketry.
Now can you demonstrate cumulative selection without utilizing a target? That was the question asked.
