Thoughts on Vimaan Shastra?

I have read the entire book, but it seems pretty incomplete, probably because of British erasing many of the parts of the book or something like that. Well i am not going to talk about that today. I wanted to discuss about the Mercury Vortex Engine, pretty controvercial topic if it comes into the practicality of the machine and its principle. There was a (or maybe is) a possibly under development spy aircraft of the US which was TR-3b, it is a triangular flying object which involves a propulsion system which works on the principle of unconventional lift, in simple words it was to use that Mercury vortex engine, there has been many seighting but they are just another low quality fake footage by some people, but there are real and actual footage released by US navy:- Video 1 :- [https://youtu.be/VUrTsrhVce4?si=LR8F7DsIrd94RX4P](https://youtu.be/VUrTsrhVce4?si=LR8F7DsIrd94RX4P) Video 2 :- [https://youtu.be/2TumprpOwHY?si=s1D1QQiDS\_fSSWcD](https://youtu.be/2TumprpOwHY?si=s1D1QQiDS_fSSWcD) we must remember these are actual declassified videos released by US Navy, the US Department of security confirmed the authenticity of the the videos and that the object in all these videos was a triangular flying object. there are also 2 patents filed by Salvatore Cezar Pais, which are :- 1. [US10322827B2 - High frequency gravitational wave generator - Google Patents](https://patents.google.com/patent/US10322827B2/enhttps:/patents.google.com/patent/US10322827B2/en) 2. [US10144532B2 - Craft using an inertial mass reduction device - Google Patents](https://patents.google.com/patent/US10144532B2/en) both of these patents are granted and their working principle looks a lot similar to the working of Mercury Vortex engine mentioned in Brihad Viman Shastra, yes these patents were filed in 2016 and 2017, but this could have been a cover up for the TR-3b as it takes at least a week to grant a patent, but both of these patents were granted the same day they were filed, well that is another topic These Patents prove that the Mercury Vortex engine is real and the fact that scares me the most is this topic is never talked about and that US is the only country that has access to this Technlogy
