I recently watched Sadhguru's video on youtube (https://www.youtube.com/watch?v=PxPlm44PCK0) where he said that Pushpak Viman(aeroplanes) was already built by us in Vedic Era.

I am aware that our great history has done many developments in various fields for example,in medicine(ayurveda),mathematics,space exploration,etc..which is in use even till this date,but it is present today, because the knowledge was taught and passed on to future generations.

My question: Is it possible that many of our great ancestors had already invented things that the world is yet to see and written about the inventions in some books or manuscripts and was forgotten?

If yes,is it possible for me to find such manuscripts and try to revive them?
