Considering it was just meant to be a proof of concept and only fly once or twice I would say that 71 flights, a max altitude of 78 ft(24 m), and 10.6 miles or 17 kilometers of travel, not to mention all of the footage from its on board cameras, makes Ingenuity an astounding success.

This fuselage failure actually happened where a door could be in the future. These locations are called plugs, if an airliner decides to add the door at some point in the future the plug is removed and a door is added in its place.

My 6s still gets software support, does it run the latest OS? No, of course not and nor should it. But Apple is still supporting/supplying my old ass iPhone general software/security updates. It’s in a company’s best interest to get customers to purchase their latest products but that shouldn’t undercut their commitment to their older products. I have stayed an Apple customer not because of their new products but because of the longevity of their old products/ support for said products.
