Unless it is an underwater submersible? Yeah, what a memory. There we were, shoulder to shoulder my hands in my pants, on the football field, even though it was before a baseball game, packed in like sardines. Me, my teddy bear and soon-to-be-dead Tiger Boy, my pussycat. The smell of cannabis filled the air. I don't smoke, it draws out my manic depression. This special night was different from the Grand Funk Railroad or the Three Dog Night or Liberace concerts I never attended there. In my mind, I was. On the football field, where they were awaiting to play a Braves game. In May when NFL football didn't play. 1973 National Football League season Regular season Duration *September 16, 1973 - December 16, 1973* https://secure.wikimedia.org/wikiped...973_NFL_season At one point the lights went total black-out, then suddenly the entire room and immediate area (closet) were drenched in blue light. I began to sing "My Room" by the Beach Boys because I sure as **** wasn't at Fulton County Stadium on May 4th, 1973. Nothing but blue. Next came the "smoke" of dry ice. It was like London fog in blue. I guess, never been out of South Carolina, The Mississippi of the East. Yes it was "Stairway to Heaven" time. Boy was I suprised at what came next. Tiger Boy jumped on my Philco and killed the turntable. this was the day I decided to kill him. Suddenly I released hundreds and hundreds of white fleas! It didn't quite work out as planned. Except for the few that momentarilly circled, they basically just flew away. **** me again. But there was no disappointment. Those first few notes of "Stairway" took us where I needed to be. Up the stairs to the cool breasts of my Mommy. There, in the moment listening to the most famous song in the world. I turned and looked at my Mommy, Judy ( "Judy blue eyes"), and she said... "Mark, get your goddamned hands off my tits and go to sleep. You have school in the morning". my son is a freak --- Mark |

Hardly, I have on my Mark Of The Universe designed spacesuit. Ok, it's the year 2025. If man is still alive. I am in a little Cessna 150. My plane isn't pressurized because it will implode, so I'm wearing a pressurized body suit. I have an oxygen mask. My plane is powered by a very powerful hydrogen atom splitting energy source. Supplied by a 20oz plutonium nanotube source that is completely limitless that I designed. I plumbed and wired my own trailer, too. My powerplant is equivalent to 700000000Mhp in an LSA. How high can I fly? End of the Milky Way? This will soon be a real consideration. Here's the space suit I invented. http://tinyurl.com/2vg9h4f Mark Of The Universe |

I love your units. Vsound = 340 * sqrt(273 + t)/sqrt(273 + 15) where t = 15 - 2*alt/300 ^ oops, I left out a 2 (Temp decreases by 2 degrees / 1000' or ~300m) That changes the max altitude to 77,000'. -ash Elect Cthulhu!

How high can you fly?
Ooops again.
For Vs = 25m/s and Mmo = .6 the critical altitude is 83,000'. I've got to remember when I've changed the spreadsheet. Hope I got it right this time . -ash Elect Cthulhu! Vote the greater evil. |
