Vaayu yaan means air travel not aeroplane. Your slight of hand here and overall comment history suggests you're parroting some right wing propaganda. Tell me something, why do people like you always find things that exist now in the past but not things that will exist? If airplanes and testtube babies are mentioned, why aren't there any mentions of things that modern society will invent in a few years, decades or centuries? I'll give you a hint: you don't have them because you can't retrofit those. Once someone invents them, then you can find vaguely related sentences in a large corpus of Indian origin and claim _there was something there_.
