  1. It's not the tool that becomes obsolete. It's the tactics. In the end unless the goal is to leave everything irradiated you still need to take and hold ground with boots on the ground. And even if you hold boots on the ground no western nation can ever win against an insurgency. Eventually the public will demand an end.

  2. The Blackburn Roc would've been even more effective seeing as it was slower. 🥴

  3. The creme puff shooting Tommy Guns. And the pedal cars.

  4. I will give Musk and SpaceX their due for their accomplishments. I also realize that or ideas of his are around. HyperLoop anyone. I also think is Mars plans are an example of idiocy. Its not that l think humans will never explore Mars or utilize its resources. Provided its a deadrock. Its just the idea that it can be done with SpaceX StarShips is a problem. SpaceX has a number of hurdles to get over. And l know that StarShips have yet to achieve LEO. None of the flights so far were planned to reach orbit. The hurdles. 1) The resuablity goal. It will be a long time before spacecraft begin to approach the turnaround time that commercial aircraft have. And by approach l mean an order of magnitude. Or two orders. 2) Engine reusability. How much inspection and checkout do the Merlin engines on Falcon and Falcon Heavy require between flights. So far no Raptors have been reused unless the next flight intends to reuse anything from the booster that was caught. Setup a Raptor on a test stand and run it through repeated cycles of flight regimens. And proposed ispections inbetween flights. Test it until it breaks. Rememder the engines are also seeing stresses from the booster returning assend first at supersonic speeds. 3) Refueling on orbit. This is big deal maker or breaker. I suspect that having the vehicles mated side to side will be a problem. How are you going to transfer the fuel and oxidizer? Both of which are cryogenic. I'm not an aerospace engineer. But it seems to me once StarShip is operational it would be worthwhile to develop a pure cargo lifter version. The cargo version launches and docks to structure that can take say eight cargo versions. The structure is then spun up to provide just enough spin gravity to make pumping fuel and oxidizer easier. House the cargo versions engines in a seperate pod that can perform a balistic re-entry for reuse. 4) The Life Support System. Just how much work has SpaceX done in this field. Probably more than we realize. And there are other hurdles.
