speed of light >> speed of sound, my comment still holds true three60
Not really - your test for whether or not he was travelling at, near or above the speed of light doesn't necessarily rule out the possibility that sky was travelling at a speed v<c that is also greater than v
s the speed of sound in air.
Labouring the point somewhat (well, far too much) but actually there is a serious point to this, that you need to be very careful when taking measurements and comparing them to the right thing. One other reason that the news article you provided a link to has the wrong solution to the neutrino problem, for example, is that the paper it cites makes use of Special relativity to try to provide an explanation, forgetting that special relativity by its very definition only applies when there is no gravity - which, clearly, isn't true when you are orbiting the Earth.
