"Air vehicle" meaning "aeroplane" is an interpretation. I could interpret it as sailing ship for example. Or a ballon. Possibly something like a chinese lampion which were already known 2000 years ago so it's not a big stretch.
In air? Then how is it better than the general characterisation as "Air vehicle"?
> Or a ballon.
Yeah, could be. And flying a balloon from Sri Lanka to Nashik(while crossing ocean) and back again would have been an achievement in itself during that period.
Why "in" air? Could just mean it's a regular sailing ship - after all they are powered by "air" so they are "air vehicles". Or it could be made out of air. In which case you could claim Indians had inflatable ships thousands of years ago :)

Of course, my point was that there are many possible interpretations and when you say no interpretation is needed you're just showing your cultural baggage.
There's a legend about Pan Twardowski. In it a nobleman makes a deal with the devil and forces him to do various impossible feats to avoid going to hell. One of these feats was "making a whip rope out of sand". Optical fiber is basically a rope made out of sand :) After that the nobleman escaped from the devil and landed on the moon (where he lives to this day).
It's pretty obvious to me that it's just a legend, but if I wanted to interpret it literally then Poles were on the moon in 16th century and had optical internet :)
