You can watch some of the recorded webcasts of the lectures delivered during the Aero India 2009 Air Show.
Though I’ve yet to watch the full lectures, some lectures that I found very interesting and am planning to watch tonight:
These webcasts are being streamed by 24 frames digital, a company that provides Video streaming service to different organizations.
You can also view some other webcast for which they had provided their services.
Note: Found some difficulty viewing the videos in Firefox and Opera. Solved it by using windows and opening the URL in Internet Explorer.
