Sorry i'm not a JPL Jet Engine Designer, nor do i have a billion dollars and 30 years to test everything just to prove things to you. Whether Oxygen can can burn - (you insist that is what i'm talking about when I'm not because it's an irrelevant issue), I did present evidence air can be used "like" a fuel source - in that it can explode, air can be separated and compressed leaving elements that are combustible or the oxygen can be used in a magnetic levitation kinda way. Thats three very plausible examples that are much more reasonable than Jumbo Jets carrying around 30 tanks fill of Jet Fuel sloshing around for these long distance flights. Do you know how much that fuel would weigh? We simply can't make airplane fuel tanks bigger, Thats why the Spruce Goose built in the 30s couldn't get higher than 100 feet off the ground, it was too heavy, so despite your ""usual" wicca-pedi knowledge, science has known about this issue for 90 years, and thats how far you are in dragging behind.
awww so cute child, now feel free to grab a sucker, I keep them in a jar in the corner of my Jet hanger.
Now you're lying to me @bold. For oxygen itself to be explosive, it must be combustible. Oxygen helps other things explode. That's why it's considered highly reactive.
Atmospheric composition is Nitrogen, oxygen, argon, and trace elements. The first three are 99.96% of the atmosphere, and none are combustible. So no, you can't just "compress air leaving elements that are combustible."
Magnetic levitation by oxygen? Wut?
I'm sorry, what exactly is "more plausible than jumbo jets using fuel?"
To answer your question about "do we know how much fuel weighs," yes, we do. You can Google pretty much any commercial aircraft and find out how heavy it is empty and how heavy its MTOW (maximum takeoff weight) is.
The Spruce Goose's operational ceiling was never determined because it never underwent further pre-production testing. It lifted off once, to prove to Congress that it could fly and thus that Howard Hughes hadn't wasted the public's money developing it.
Is there anything else you'd like to be shown how you're wrong, today?
