alpha2 Posted March 31, 2018 Report Posted March 31, 2018 (edited) Ah! the Galaxy Song! "splains" so much about things. Catchy tune. Oh, and I rounded the numbers on the times. It's actually close to 1:06.5 outbound, and :54.5 return. The E6B Flight Computer is your friend. (See pic). Commonly referred to as the "whiz-wheel". Back before GPS made such things obsolete. Except for pre-flight planning, of course. WOW, I keep finding more and more things that say to me, "you are SO obsolete, dude!" First Morse Code, now this. I am dismayed. I just had an "interesting" half hour trying to explain this to my trophy wife. Ended up using the moving walkways at Denver International Airport as an example. Better than the hour we spent at the end of the grass runway in Frankenmuth, Michigan, explaining why we always take-off and land into the wind. That one required relating to money in your account in the bank. Starting out with a balance, as opposed to a deficit. THAT she understood! She's all about the money.

Mjolnir Posted March 31, 2018 Author Report Posted March 31, 2018 so this is why a plane can take off from a stationary position on a treadmill?

Mjolnir Posted March 31, 2018 Author Report Posted March 31, 2018 PS if you can see expansion with a telescope then its an optical illusion. it is contracting. and not the building a house kind.

We're not getting into THAT bit again! The all time winner, as I recall, on an aviation forum. (But, it is related the "groundspeed vs. airspeed" thing). And, well, rolling wheels, vs. driven wheels. And, a few other things. Co-efficient of friction had nothing to do with it. (What makes an airplane fly? MONEY!) And, the expansion was not a direct visualization, it was a visualization of velocity change, via red shift, if you believe in that sort of thing. (Totally unrelated, remember "Red Dwarf", the Brit show?). Wow, talk about thread creep! Eh? Quote So much leather...so little time.

bermudahwin Posted March 31, 2018 Report Posted March 31, 2018 Do I recall Ouroboros/Mjolnir type plot in Number of the Beast?
