The most dangerous part of the launch process isโฆwait for it
MAX-Q
or maximum dynamic pressure
The max q condition is the point when an aerospace vehicle's atmospheric flight reaches maximum dynamic pressure. This is a significant factor in the design of such vehicles because the aerodynamic structural load on them is proportional to dynamic pressure. This may impose limits on the vehicle's flight envelope.
Dynamic pressure, q, is defined mathematically as
q = 1 2 ฯ v 2 , {\displaystyle q={\tfrac {1}{2}}\,\rho \,v^{2},} q = \tfrac12\, \rho\, v^{2},
where ฯ is the local air density, and v is the vehicle's velocity; the dynamic pressure can be thought of as the kinetic energy density of the air with respect to the vehicle. For a launch of a rocket from the ground into space, dynamic pressure is
zero at lift-off, when the air density ฯ is high but the vehicle's speed v = 0
zero outside the atmosphere, where the speed v is high, but the air density ฯ = 0
always non-negative, given the quantities involved
Therefore, (by Rolle's theorem) there will always be a point where the dynamic pressure is maximum.
In other words, before reaching max q, the dynamic pressure change due to increasing velocity is greater than that due to decreasing air density so that the dynamic pressure (opposing kinetic energy) acting on the craft continues to increase. After passing max q, the opposite is true. The dynamic pressure acting against the craft decreases as the air density decreases, ultimately reaching 0 when the air density becomes zero.

had an old training manual but this was easier to find and post.
It is worked as a contractor but not on active flights-many hours in sims and know this well.
Surprised the ex-nasa anon did not mention.
he is correct in what he said however I am surprised he did not mention this.
for sure. do not want to go into who I worked for and it was not nasa however let's just say it was heavily connected to them and it involved kids.
have had a few professional lives IYKWIM.
If you saw the picture of J Lovell a few breads back that was mine.
mis-fire previous
not at all. It's normal to be somewhat skeptical.
I am a little skeptical that he has not tagged that or confirmed it. I also know that working at nasa is highly compartmentalized as well. Not doubting that experience but my spidey senses are tingled a bit.
I am no one special and also not that old too. Had much experience early in life and did many things.
