With China nowhere in sight in this technology which has only been tried by US and Australia, China is already very much behind India in the space race. US and an "incompetent" Europe keenly watching all developments and with India's remarkable superlative achievements, the future belongs to India !
When US spent $195 billion on its failed space shuttle mission, at an effective cost of $1.35 billion for each of the 135 space shuttle flights, India is going to surprise the world with a scramjet powered shuttle in the coming days.
ISRO's mission to the sun is the next biggest thing to happen to humanity ..
There was an attempt to arm US' Tomahawk with SCRAMJET engines. But we do not know how many Tomahawk missiles are with these scramjet engines, as publicising the existence of SCRAM jet supersonic missiles is a threat to US itself.
