Auto Credit Based on kikasshes's [CLOSED] Mach challenge

This is my entry for the mach challenge. I had one goal for this plane - to fly at mach 3 without modded engines. This plane can do 2100mph+! I have clocked it doing 2116 at about 42000ft. At this altitude sound travels on average at 659.8mph, making this plane capable of flying mach 3.25+! The sweet spot for top speed is between 38000 - 42000ft. Takes off at 300mph breaking mach 1 before it leaves the Runway and can make mach 2 going completely vertical. Thanks!

@Puredeath I just modded this aircraft to have 23 turbofan engines (this one has 9) and my top speed was only around 2170mph! I think this speed is probably the highest speed that can be reached within reason, because at some point adding engines only gets you a couple mph further,which doesn't justify the losses in weight from more engines and fuel

@Puredeath well it'll be hard to top that if you can pull it off!

@kikasshes @lowobservable I have a plane that i am currently working on that will go over 2200 mph at 50000ft or so, currently trying to push it towards mach 4 though (2636 mph or so)

@lowobservable Yeah, but ideally I would like to fly from Murphy airport, reach top speed, turn around and then land at Murphy airport again.

@kikasshes thank you! Yeah it was hard to get more fuel on the fuselage, too many engines! There's enough fuel to make it to the island and make top speed so i figured it's be enough for the challenge

This is just amazing! You are far ahead in the lead! One complaint though; the fuel is burnt very fast.
