Astrogator, would you be so kind as to add the launch costs for the Evacuator 40 and 100?

Astrogator, would you be so kind as to add the launch costs for the Evacuator 40 and 100? Forgot, sorry. Please don't be too polite, I don't like it.EVC 50: 76,800 c/seat EVC 100: 56,100 c/seat EVC 1200: 47,500 c/seat EVC 1800: 44,278 c/seat (actual cost: 44,277.77... c/seat) We began to construct our tanks out of graphene, and reduce the cost and weight, freeing more mass for delta-v. Class: FutureEvacuator 50 Evacuator 100 Evacuator 1200 Evacuator 1800

Argopeilacos: Earth Escape -- 37,960.00 ¢/seat (196 passengers, 54 crew; 9.49 Mc) Don't forget the 200t cargo bay! That thing could be much cheaper without it.

You people are forgetting that this is a MASS evacuation. Stop thinking small scale and start looking at ECONOMY OF SCALE!CHALLENGE ACCEPTED Given this ship's biblical size, I gave it a rather biblical name to match.

Stop thinking small scale and start looking at ECONOMY OF SCALE!CHALLENGE ACCEPTED Given this ship's biblical size, I gave it a rather biblical name to match. 'We've received a report from Mojave spaceport that a giant untested spacecraft, named Exodus 1, has broke down and blew up in the middle of the air few kilometers above the surface, killing all of its 20,000 passengers and damaging nearby launchpads. This is most likely due to its immense size and its armor, made of magnesium, which is combustible. The spacer engineers are probably too rushed to account for ship weight into their simulation, and this is the result.' - A report. Seriously, be careful while constructing these kind of stuffs...

You forgot the aerodynamic nose nerd1000 . That's your main concern with this design? Also, it's probably not as important as you might think: Edit: Fixed

A quite unusual rocket as i never saw rocket with nose like that. BTW did i just saw the phase " titan liner" in your design list?

idealy you'd have varible thrusters to avoid turning the passengers and crew to a red paste

Feel the need to write something Concept, Launch Vehicle Construction: Safety'In the state of impending emergency, nobody cares to have a good ride. Hundreds of people would crunch into a single rocket just to survive. Rocket designs with extremely tight delta-v limit could not hope to inject itself into space. As shown by the Children of a Dead Earth's The Cataclysm event, safety is also a limit. Cheap, mass producing rockets tend to have very high failure rates of around 1/20, while the more delicate rockets, built by more experienced engineers and more sophisticated technology, the rate is around 1/100. Building and launching to slow, though, is problem, too. Japanese rockets retain their pre-Cataclysm safety (when excluding the assassination of the Japanese prime minister, the failure rate is zero), but by being relatively small, it could only evacuate a tiny fraction of its population into space. It is important to find balance in between these two limits. Even such emergency event doesn't exist in Children of a Prosperous Earth yet, it is important to learn, in case if there is any urgent need to evacuate people out of the planet rapidly. Technological advances will help, but we'll have to do the rest.'
