We can make rockets but not helicopters. Why?

Two days back, on Sunday, India successfully launched its first Geosynchronous Satellite Launch Vehicle, or GSLV, from Sriharikota. India has been successfully launching the Polar Satellite Launch Vehicle, or PSLV, for a long time but it took 20 years of hard work to make this a success. The GSLV can carry a much bigger payload but needs a cryogenic engine using liquid hydrogen at -253 Celsius and liquid oxygen at -183 Celsius and is a difficult technology to master. The reason why it has taken so long is because the US applied pressure on Russia not to transfer the technology to India and the scientist, Nambi Narayanan, who was in charge, was arrested on trumped up charges of espionage. US enmity is nothing new for India and did not start with the sexual assault of our diplomat. While it blithely turned a blind eye to Pakistan acquiring nuclear weapons, masterminding the 9/11 attacks on the World Trade Center and constantly assisting the Taliban in killing US and NATO soldiers in Afghanistan it has consistently taken a hostile stance against India. Trouble is that many of our politicians have large amounts of money stashed away in western countries and like to travel frequently to the US where their children are studying or working, so they are unable and unwilling to take retaliatory measures. Already the worms are gnawing away at the achievement, saying that it was only partial success because the payload was not big enough. The mystery is that while we seem to have mastered rocket and missile technologies we are unable to develop our own aircraft or helicopters. Tejas, a light combat aircraft is being developed since 1983. The government has just announced that it is canceling the contract for Agusta Westland helicopters worth Rs 36 billion because the company had paid bribes to obtain the contract. Only 3 of the helicopters have been delivered but the government has already paid for 5. The government is now looking for more luxury helicopters for VVIPs because they do not have enough spares for the Agusta copters. We could have been making our own helicopters, aircraft, both military and civil, ships and submarines if they encouraged our private sector to make them. When we are buying from private companies in other countries there can be no reason why our companies should not be in the business. But then there would not be billions of rupees in bribes. When you have sold your soul it is easy to sell the nation.
