No doubt it is a great loss to the exchequer and certainly difficult to afford . But the point is that the surest method to avoid failure is "to not try". So shall we as a nation just sit idle and save ourselves from failures? People who are questioning the credibility of our esteemed scientists should rather wake up. Please remember Rome was not made in a day. It does not take a penny to criticise in a democracy,but those who have nothing better to do than to just criticise should remind themselves that it is only because our foefathers tried , failed , re-tried untill they succeeded that we are enjoying the fruits of developement.
