It’s simple. You cannot put anything into the air besides a hot air balloon. At best you can create a glider and glide down from above, but the idea that you could build a machine heavier than air that could hold a person a motor and fuel combined is ridiculous.
Just think of the weight of the fuel alone! Gasoline weighs over six pounds per gallon. To have enough gasoline to push against the ground with a motor or fan of some sort would require monstrous gasoline consumption.
It is utterly ridiculous to imagine that you could do anything useful with a machine and flight. The machine itself, the motor, the fuel and the pilot simply are not sustainable.
Not only is it physically impossible, but dear god, it’s a foolish venture to attempt to make such death traps into a business. You could never produce an actual plane that could carry itself for long, let alone cargo, people, or get anyone to pay to have the gargo moved that way. Anyone who shipped via an airplane would surely loose their valuable posessions that way. And comfort? What kind of comfort could you experience from falling out of the sky?
No, sir, no. It is clear that rational human beings should stick to balloons.
