stealth B2 bomber
The nightmare of every enemy country in the world. It came at a speed of 1100 km/hr, cut all the radar and other defense systems, flew low very quickly, destroyed everything in the sky, even as this American bomber disappeared, the army could only think ‘what happened now’.
No vanity no mantra. One is nature and the other is technology. Both are based on scientific principles.
