May 11, 2020 at 22:54 | comment | added | Russell McMahon | Related: Air density decreases logarithmically. Density halves at about every 14,000 feet (so it's about 25% at the height of Everest.) Subsonic energy dissipated rises with cube of velocity and supersonic "it gets complex. So energy load is dropping with log altitude, rising with speed cubed and power (rate per second) dropping per energy rate as duration for a given region gets less as you transit it faster. Overall you get a rising "pulse" which then drops rapidly. On reentry you enter the same density regions at higher velocities and then slow more rapidly than you accelerated. | |

May 11, 2020 at 16:41 | comment | added | JYelton | I did not expect this question to have the complexity in answers as has become apparent. @DrSheldon I do usually wait a bit longer, but I initially felt since this was a "simple" question, that GdD had provided a clear, if simplified, answer. I will re-evaluate my accepted answer. | |

May 9, 2020 at 3:03 | comment | added | DrSheldon | Please consider giving more time for answers to be written before accepting an answer, instead of picking the first one that appears. In particular, it is a good idea to consider whether an answer is supported by authoritative sources. | |

May 9, 2020 at 0:18 | comment | added | JYelton | @Russell I did look around for something first. I've noticed that the searches on StackExchange seem to leave a bit to be desired. (On Electronics, I rarely can find questions even when I am certain of keywords and words in the title.) | |
