IS it on or is it off? No one in the government seems to know, far less the aviation industry. Two months after the Union cabinet finally sealed the fate of the ambitious Tata-Singapore International Airlines (SIA) proposal saying equity from foreign airlines will not be allowed directly or indirectly in domestic air services, the jinxed project seems to have bounced back with a signal from the most unexpected quarters-I.K. Gujral. The Indian Prime Minister, on an official visit to Nepal last fortnight, spelt out his point of view, without a clear 'open sky' policy, it would be difficult to think in terms of real economic development. The current aviation policy, he said, was too obsolete and needed drastic changes.
