Onhwy61, I read the Wiki link you posted, including the section titled "Drum Sound", and I could not find any reference to two drummers and a drum machine being used on "In The Air Tonight". All I found was an explanation of the drum sound being an accidental discovery during a Peter Gabriel recording session when Collin's drums were accidentally recorded with the recording engineer's talkback mic engaged, which resulted in the drum sound that was later replicated on "In The Air Tonight".
Maybe, you would cut and paste the two drummer, drum machine reference.
