Except for that the reply doesn't actual counter any of the analysis made in the sceptic video, but instead criticises Mike for taking a sceptic approach and disregarding the audio from the pilots (because they essentially see the same thing as we see in the video). This is the typical approach one sees over and over again from most people invested in some sort of conspiracy theory, they never reply to technical criticism, but instead either switch to some other "evidence" or criticise the sceptic for "not taking an open minded approach".
