In the book "Ignition!", John D. Clark describes how a person could have a red fuming nitric acid exposure, apparently be okay, then drop dead a few days later. www.youtube.com/shorts/Ygyob...

A spaceship accelerating at 1g for only one hour would reach 79,000 mph. Escape velocity from the solar system is 94,000 mph. So basically the practical limit for 1g acceleration is a little over an hour.

Leduc 0.21 French ramjet plane completed a very detailed flight test program from 1953 to 1956 to develop automated, operationally viable throttle controls for the ramjet. This included a total of 284 free flights. Designed for subsonic speeds only, the 0.21 reached a top speed of Mach 0.95.
