Can't stop laughing ! Big time BS !
Does he even know what gravity and electricity means ?
I came across similar BS story somewhere in Nepal, it was entitled "Ultralight".
Objective -> To build even lighter than the existing ones (at least I suppose).
According to the article, of many other things he was using " फलाम = Iron/Steel.
For starters, go learn periodic table of elements and their properties, there is Aluminum (lighter metal) and other alloys.
I was reading the comments as well - and one can group these comments/people into two categories (excluding the ones who didn't buy the news for obvious reasons) -
1) Those who are praising/supporting this BS and blaming the government at the same time.
2) Those who are praising/supporting this BS and ranting our neighbor India.

I kind of relate the first part "praising/supporting" due to ignorance/emotion !
But, second part, seriously why do you bring unrelated stuff ??

I'm not sure if there is one, but shouldn't there be a legit column in some national newspaper/magazine dedicated to science (the real kind) and related stories.
So, as to discourage these kinds of BS and encourage the real ones !
