I don't think they forgot about it, or are covering anything up. Perhaps they've been persuaded the gun reports were in error.
Or perhaps the reports they've provided all along are correct, and the confusion is with the friend who incorrectly mentioned a gun.
Keep this in mind as well: We both agree Deena Burnett relayed the report of guns, probably in violation of an order to keep silent.
I certainly don't agree with the "probably".
Yet in all the years since, she has not brought that subject up-- not in her book, nor in her numerous speaking engagements. Therefore, for others in her position to likewise refrain from mentioning that point does not in any way show that it didn't happen.
Not brought what subject up? Reporting that Tom said one of them had a gun? If that's what you meant, you're incorrect.

So you're saying maybe Olson from AAL77 (Renee May?) mentioned guns in her allleged calls; and that Peter Olson maybe did as well from UAL175?
There's a second hand reports from the operator who relayed Barbara Olson's call (search for Mercy Lorenzo on 911myths), and a third-hand report from this friend of the Hanson family, yes.
So now we have (at least) four gun reports from the four flights, and yet you still doubt the possibility that the hijackers had guns, because the Commission "looked into it" and didn't concur?
Not just for that reason, no. As I said, first-hand reports of the Hanson and Olson conversations, which I'd consider more reliable, don't mention guns. The FAA memo "gun" reference was disowned by them and the person who wrote it. No-one else on Flight 93 reported guns. There are no reports of guns being recovered. And so on.
You can doubtless hand wave away much of this, but the idea that relatives, if they were told by their family member that there were guns on board, will just accept this was a "mistake" and not mention it strikes me as very unlikely.
And the fact is that we can see they're able to mention this. Deena Burnett said "one of them had a gun" in press reports from the beginning, she repeats that in her book, she repeats it on Tom's foundation site.
There's no reason to believe that the relatives are being made to keep quiet, then. I think they're all repeating exactly what they heard, and on the balance of that evidence - all of it, the first hand accounts - it doesn't seem at all likely to me that there were guns on board.
