Pressure may be "near" 0, but what causes one to state essentially no wind when considering the speed at which the rocket is going? The speed of the rocket has nothing to do with 'wind'. Take a physics course. I knwo the stack reached a peak of 93km altitude (where air density is very very very negligible) but unsure on what altitude the incident happened. A little over 130,000 feet is where staging occurs. This is preposterously easy to find out. Scouring through Russian SpaceWeb, I find booster separation at roughly 118 seconds happens at roughly 48km altitude. This is when the incident happened. See? Like I said. Ridiculously easy to find. Even you managed it. So air density wouldn't be so nill at that altitude considering the speed rocket is going at. The air density also has nothing to do with the speed of the rocket. It is what it is. Pressure at that altitude is around 0.04 psi. That qualifies as a medium quality vacuum. -- "Ignorance is preferable to error, and he is less remote from the truth who believes nothing than he who believes what is wrong." -- Thomas Jefferson |
