Re P channel issues - it was in one of the Satcom System Specification Manuals, referenced way back, can't find it just now.  Go over to Victor's blog, they have mentioned it again.

Also note this.

The "possibility" that the BTO's we have been given may have been "altered" raises it's ugly head again, particulaly in light of the fact that:
(a) Inmarsat never replied to Jeff Wise,
(b) Inmarsat refuses to discuss the issue,
© Inmarsat refuses to release their logs,
(d) Inmarsat held firm at all news conferences that ALL data had been given to the "Official Investigation", so go ask them,
(e) Since the ISAT data is "key", the fact that Inmarsat has steadfastly, to this day, maintained a "Pontius Pilate" attitude, is worrying,
(f) Even in their "own" paper in the "Journal of Navigation", you will note that EVERY reference they use, is from "the Official Investigation" documents, note, NEVER any of "THEIR OWN".

You have to wonder, what kind of reputable organisation, uses questionable outsourced data, in a bid to explain the workings of their own system, to the general public, unless there is need to hide something, or they have been ordered to do so (by some government), or both.

The very fact that the article was published in the "Journal of Navigation" in the first place, instead of some Satellite Industry Publication, is suspicious in itself.  Is this "a clue" in and of itself ?

Then - consider this.

Smoking Gun - BTOs were possibly changed - perhaps this is why INMARSAT refuse to discuss.JPG Size: 31.45 KB  Downloads: 125
