I didnt say HAL should build a plane in A380 class. Let me summarize my viewpoints..
1. Time to fly trains with 1000 seat capacity- By this I meant, we need to thing out of the flow. Lets not be follower everywhere, must need to lead somewhere when it comes to scientific innovation. We are 1.3 billion people, and if these many peopel cant think about flying a train in the sky [for example] then better we place an order with Airbus and Boeing for rest of our life and HAL's current and new generation employees can easily retire doing job work for them!
2. 90 seat plane is like an auto rick - By this, I tried to raise a point that we are using very conservative figure as benchmark for our maiden civil airplane...90?...In 21st century if we start off something with such a low benchmark, [even its a reinvention of decades old invention]god save our future.
So, there are two thing, think out of the box and think big. Thinking small and experimenting (in fact following or copying) with small number is fine at academic level not at professionally run aero engineering company which is also Asia's one of the largest aero companies!
