I disagree Skoshi.

I do not want to go into physics and btw physics won't explain all as we would also have to look into how the brain processes the input from the ears and also we would need to understand how the ear works.

Fact is that there are piles of evidence from pilots' narations, pilots that actually have flown combat missions, which are all clear in one point: they could not hear other planes.

I cannot understand why people continue to reject first hand accounts in order to preserve some sort of sound radar and present sound radar as realistic.
