They say in the video (link below) that the space shuttle is reaching the speed of 12.000mph more than 4 miles per second. its around min 7-8 in the vid. I dont look forward to see if the speed increase, lets take this data 4miles per second.
- A bullet max speed is near 1500m per second
why i cannot see a bullet but i can clearly see the shuttle? there is tons of videos of it even if it travel more than double the max speed of a bullet
why the crew in the shuttle doesnt care and even laugh at certain point? they dont need oxigen mask (jet pilot do with less speed and they can even pass away), they affected by 3 times the force of gravity on earth but they seems so cool, they move like everything is normal
what are they reading while travel at 4miles per second? do they need instruction on how to fly that thing? how can they read with all that forces going on?
To me seems really weird, but i lack of knowledge in how speed and G force affect the human body. If you know sure things pls help.
