The modern jet engine is the most fuel efficient engine developed for miles traveled per pound. Contrails are water vapor, created by burning fuel in the engine. Secondary contrails can occur off the wingtip vortices as high pressure air from under the wing meets low pressure air at the top of the wing at the wing tip, effectively squeezing out moisture from the air. Contrails are liquid water squeezed out of the air, either by compressors in a jet engine, or by wingtip vortices. Burning hydrocarbons also create water as exhaust.
Trains are slow and impractical for the huge expanse between cities in most of the U.S. They are great for freight, however, if time isn't a major factor in it's delivery. Great for that bulk freight like coal, shipping containers of imports, grain, etc. The modern locomotive is the most efficient engine in terms of weight moved per mile. Both engines use oil for fuel (kerosene for jet engines and diesel oil for locomotives).
Why would anyone waste three days on a one day trip in business??
Fly there, do your meeting, and fly back. Same day. Be home with your family that very evening. A private plane makes that even easier.
No hotel room needed with a one day business trip.
You could always ride your horse to work too. Saddle up your good buddy, enjoy the sun as you trot along the road to your job, get their by the time everyone else is going to lunch, get fired for showing up late, and trot back home to enjoy your retirement, then get fined by the city for leaving horse droppings everywhere.
You are reversing your own numbers.
Is they why most of them fly?

Hiding Joe doesn't get to decide what people will use for transportation. He is not the king.
Joe understands very little. You should see him without a teleprompter. Even WITH a teleprompter he manages to fuck up.
So?
A commuter train is not replacing air travel. Special pleading fallacy.

Global Warming violates the 1st LoT by claiming a magical creation of thermal energy out of nothing, in the form of a temperature increase, which is somehow caused by a magical substance.
Greenhouse Effect violates Stefan-Boltzmann and black body science by claiming that an increase in earth's temperature is somehow caused by a decrease in earth's radiance.
Greenhouse Effect violates the 2nd LoT by claiming that the cooler atmosphere somehow heats the warmer earth's surface.
Bullshit..........Climate change my ass............5 gallon gasoline can armed arsonist terrorists have been caught red handed starting many of these fires....and then released by Soros funded DAs to go back on the rampage again. One individual was caught....released and then charged with starting at least 5 more fires.
Even with the spinning coming from leftist news sources....the truth comes out usually near the end of the article after they have spent 95% of the article declaring We are not seeing any indications of a MASS politically influenced arson campaign, but......"A number of wildfires in Washington, Oregon, and California are now being considered ARSON....and several ARSONISTS are already in jail - while there are others on the run." SPIN BABY SPIN. Yeah those systematic racist police are guilty of conspiracy..... Climate change? It could never be the fact that the federal dollars donated via US TAXPAYERS across the nation was misused and none of these left wing managed forests have been managed correctly for almost 3 decades now in allowing the brush undergrowth to go unchecked......making these unmanaged forests nothing but dried out match boxes just waiting for a spark and the proper wind. Now these winds that come every year are due to climate change?

Climate change. LMFAO. I think the citrus growers may want to have a word with this bright bulb.
Don't be afraid to see what you see

Hello T. A. Gardner,
Back when America was great again?
We don't know, exactly, what is meant by that.
Trump never specified when, exactly, America 'was' great.
What year?
What decade?
Why can't that question be answered?
What? Are all those Trump supporters just chasing an ambiguous slogan that can mean anything you want it to mean?
I have to wonder when the Black supporters of the president think things were 'great' for THEM?
How about you?
What does that mean to you?
1900?
1950?
1968?
1982?
When do YOU think America 'was' great?

Back where there were no labor laws, most people were illiterate, and the average life expectancy was about 45.
1945 to about 1960?We don't know, exactly, what is meant by that.
Trump never specified when, exactly, America 'was' great.
What year?
Does it need to be? It's a good campaign slogan. A lot better than "Build back better" whatever the hell that means. Or, Biden's favorite personal slogan, "I'm the guy..." That one is like listening to sea stories or amateur fishermen talk...What decade?
Why can't that question be answered?
