It was an era when the nation was enamored of the prospect of one day building our own versions of saucer-shaped aircraft. But the idea actually dates back to an obscure patent granted in 1898 to one F.A. Jone -- a rare bit of archival history recently highlighted by blogger John Ptak. Ptak notes (based on the patent drawings): "From the ladder that led to the major axle we can infer that the aircraft was at least 60 feet high, which made its disk apparatus a very ferris-wheel-like 40' or 50' in diameter."
Unfortunately, almost nothing else is known about the mysterious Mr. Jone (including why there's no "s" at the end of his surname). But I think we can safely assume that his patent design was never built -- and even if it was, it wasn't operable.
It's that whole vertical takeoff and landing thing, combined with sharp, sudden forward propulsion, that's the main sticking point (and also the biggest advantages if we could just overcome those technical challenges). Those are difficult maneuvers for an aircraft to pull off in quick combination, even for helicopters, which can become unstable especially in high winds. Physics always demands some sort of tradeoff, it seems.
The Samara Sutradhara is a scientific treatise dealing with every possible angle of air travel in a Vimana. There are 230 stanzas dealing with the construction, take-off, cruising for thousand of miles, normal and forced landings, and even possible collisions with birds. In 1875, the Vaimanika Sastra, a fourth century B.C. text written by Bharadvajy the Wise, using even older texts as his source, was rediscovered in a temple in India. It dealt with the operation of Vimanas and included information on the steering, precautions for long flights, protection of the airships from storms and lightening and how to switch the drive to "solar energy" from a free energy source which sounds like "anti-gravity."
The Vaimanika Sastra (or Vymaanika-Shaastra) has eight chapters with diagrams, describing three types of aircraft, including apparatuses that could neither catch on fire nor break. It also mentions 31 essential parts of these vehicles and 16 materials from which they are constructed, which absorb light and heat; for which reason they were considered suitable for the construction of Vimanas.

Ancient Indian Texts
Seems to be pretty damning that the ancient texts were "re-discovered" in 1875
A study by aeronautical and mechanical engineering at Indian Institute of Science, Bangalore in 1974 concluded that the aircraft described in the text were "poor concoctions" and that the author showed a complete lack of understanding of aeronautics.

OMG looks like nobody cared to read the actual patent. It is a friggin lens-shaped balloon!
Yes, balloons have been quite popular in the 18-19th century.
