ACARS message format
www.pentestpartners.com...
In plain old ACARS all messages are broadcast to all devices (that are in range of the same transmitter at least) so there is a header that lists the destination aircraft registration. The receiver on an aircraft will discard any messages that are not destined for it.
In the header, there is a two character label field which indicates the type of data that the whole message contains. There’s no specific standard but there are some common ones like C1 which is a message for an onboard printer, and indeed some airlines will use different labels to indicate the same data.
The bulk of the transmission is taken up by the message text itself up to a maximum of 220 characters.
The character set is basic ASCII alpha numerics and some special characters only.
These could just be standard free text type messages, or they could be engineering and maintenance data.
Message integrity
The last part of the message is a simple checksum, this is either ATN-32, which is a modified form of Fletcher’s checksum, or a CRC.

"ULMSG" are from airline to ARINC, to be routed via a target radio station (Target Stn)m which could be the wrong one; it's probably determined by airline from flight plan
"ULBLK" are messages from ground station to plane - the actuak ground station sending is in the tag "Stn="
"DLBLK" are messages from plane to ground station (downlink). The actual receiving station is in the tag "BepStnName="

I literally just laughed out loud at how absurdly stupid and irrelevant this is.

Sorry. All you have is truth movement lies concerning ground stations trying to send messages to a destroyed jet.
This isn't my "argument" you dolt, it's Ed Ballinger saying so. And Michael Winter who explained how the RBS are chosen.

The last DLBLK message from UA93 was received at 10:01:57/59ET by ground stations Pittsburgh (ca. 80 miles from Shanksville) and Washington-Dulles (ca. 150 miles from Shanksville).
After the crash time, there are no more DLBLK messages, only uplinks.

Do I look ignorant showing you what the government actually stated??

Your the one fabricating evidence that isn’t supported by the actual ACARS logs and protocols.
Sorry. All you have is truth movement lies concerning ground stations trying to send messages to a destroyed jet.
Anyone with any integrity at all can see how little of it you have, because this is an utter lie.
EVERYTHING that I have submitted is taken from the official evidence provided by the 9/11 committee.
evidence provided by the 9/11 committee. Saying that I am making stuff up is a textbook example of gaslighting
I have simply repeated what others told the 9/11 commission.
The ACARS messages that I typed out are exactly as they are shown in

This is official government evidence.
The statements I made were based on what Ed Ballinger said, I made nothing up.
But OK...you've made your point on ACARS. Several times with 100s if not thousands of words. We get it. You can have that. ACARS messages do not say what Ballinger said they do.
Therefore, I'll let you decide whether or not you need to keep harping on the ACARS evidence or not.
This categorically untrue and I will once again for the third time list out the OTHER evidence which you have heretofore (like that Wads?) ignored
The why post a hack version of this?
I posted from the evidence of the 9/11 commission and linked to it. If you can't be bothered to click on the links, I can't help you.
If you can't be bothered to click on the links, I can't help you.
I have linked ALL of the testimony I've stated. It's there for you to look at.
Are you just copying and pasting stock arguments, because we're talking about UA93, not the white jet etc...are you trying to muddle the waters on purpose. Nevermind, I already know the answer to that.
It's funny that in telling me I'm a hack and a liar, you're really just calling the 911commission liars.
What else do you think the 911 commission lied about?
