N1 had too many relatively tiny engines bundled imo and maybe so has Musk's Starship. Detonation altitude anybody?



Consider a 747 upgradeĀ  with 20 engines, go figure :-(.



Spaceship size matters to go colonize the heavens of course.



What about designing/building a bigger "F6"= 6*F1 engine ? Next bundle such Saturn- or honeycomb wise using only 5 F6 engines/stage or so.



Not hundreds of liquid engines in propellant pipes like that Germant launched in the Lybian desert and Congo. Became a bank scandal in the eighties.

He launched a bundle of max 8 only. Next he got kicked out of Africa likely plucked like a chicken.

John Carmack had a chat with him in the US a decade ago. Forgot his name.

It sure seems that flight termination was very clean and deliberate. Two clean explosions a few seconds apart. Is it possible that the loss of several engines meant that altitude and velocity was not adequate to satisfy successful flight parameters, the safety system would not allow separation, but instead, demanded explosive termination of the booster and the second stage flights? I dont think it was a rapid unanticipated dissasembly- it seemed clean and clearly deliberate.




If the second stage had inadequate velocety and was separated and ignited, it might have ended up .... anywhere? and that would not be good.





So success is impossible, get it over with with minimal threat to others.
