No, they're not chemtrails you idiots. Solar path: bzzzt.
This doesn't mean having planes is a good idea. Lunar path truth: get the planes down. If you were awake on 9/11, you could feel Gaia breathe a vast sigh of relief during the following few days, when every plane was grounded.
I have no idea why jetliners are profane. However, they are clearly very, very profane. I don't think there's anything wrong with more private planes, such as your everyday cessna.
However, this doesn't mean we have to give up aeronautics. It means: use zeppelins instead. Yes, the Hindenburg was sabotage and scam. Hydrogen blimps are perfectly safe - safer than planes, for example. They don't have to spend fuel staying up, so they can use only the going-forward part. P.S. solar-panel zeppelin: fly nearly for free.
P.P.S. Broke: flying car. Woke: personal blimp.
P.P.P.S. Broke: motor home. Woke: flying solar-powered house.
P.P.P.P.S. Flying nuclear-powered house.
