Computers Quote by Joseph LeConte
“Is it not demonstrated that a true flying machine, self-raising, self-sustaining, self-propelling, is physically impossible?”
About This Quote
The claim that a self‑sustaining flying machine is impossible challenges assumptions about physics and engineering limits.
In simple terms: Self‑sustaining flight is claimed impossible.

A Different Perspective
Technological advances may later prove it possible.
![“One: There is a low limit of weight [of about] 50 pounds beyond which it is impossible for an animal to fly. Two: The animal machine is far more effective than any we can hope to make. Three: The weight of any machine constructed for flying, including fuel and engineer, cannot be less than three…” quote by Joseph LeConte](https://sms4smile.com/quotes/img-quotes/296/joseph-leconte-73855_animal_one-there-is-a-low-limit-of-weight-of-ab_585346.jpg)
