Great read very informative. Are you aware rockets hit speeds 10x faster than a speeding bullet to get out of earths atmosphere? At least NASA tells us this, the human mind boggles as to how human bones are not crushed under the amount of pressure exhumed by 1.2 million pounds of of thrust . I've been doing some calculations and there's some interesting numbers coming about that do not make sense...anyone interested look up the Apollo 11 specs keep in mind humans were on board and passed through the Van Allen radiation belts unscathed. I'm very sceptical.
