The crux of the fresh outpourings on the project—admittedly the most contentious since Indian Airlines (IA) grounded its state-of-art A-320s in the late '80s—arises from an informal exercise started by Union aviation secretary M.K. Kaw recently. This included setting up an advisory panel which took detailed 'opinions' from senior Civil Aviation Ministry officials, people outside the ambit of the government circles and private airline operators on what could be done to open up the skies and the scope and justification of including Tata-SIA in the scheme of things.
