It was done after the whole of India cried foul and blew horns about the massive "humiliation" it felt due to this video. face it, Your nation likes to cry about little things,big things.. anything.
Any nation with greater self esteem would have invited the US back to India to prove otherwise instead of making the media and diplomatic showboat that is usually done in India.
Even I think the Indians have good and excellent pilots, There was a certain downturn during the economic boom and some pilots were lost to the airlines. But others have stayed and are fairly good at their jobs.
I have already stated my opinion about the red flag video earlier. And from my point there were some very praiseworthy points in it for the Indian pilots. Sadly, the whole of the Indian media & the nation in general only wished to see praise and praise alone.
