ACARS is a one way system. It doesn't send an acknowledgement, unless the pilots send the message. There's a long thread here about it.

My position again is that Pilots say one thing and debunkers say the opposite.
Pilots say ACARS technology is a "two way" system (to borrow your term).
You clearly have no idea what those words actually mean for ACARS - pilots do not say anything different from debunkers - it is just that you do not understand what either of them are saying!!
Thanks you for providing a perfect example of how "truthers" use their own ignorance as if it were evidence of a crime - whereas the only "crime" here is that you still spout this rubbish.edit on 6-12-2013 by Aloysius the Gaul because: (no reason given)
1/ The messages were sent TO the aircraft - that is they had the aircraft addresses on them. That does not actually require the aircraft to exist!! Seriously - just like you could get on a ham radio and send out a call for a non-existent station or similar.
A dispatcher-initiated message that reached the plane but not crew acknowledged stating "I heard of a reported incident."

You think that a few hundred people aren't going to put 2 and 2 together, realize that they just worked on a system that killed 3,000+ of their own people, and not say a word. Ever. To anyone. You're talking civilian workers, that don't fall under an NDA normally, and don't go through any kind of major security check to get their job. Not one of them has ever leaked anything like this, 12 years later. That's impressive to say the least.
It's a timestamp acnowledgement of receipt, not a physically sent acknowledgement, like the email system which shows you that it went, and made it (otherwise kicking back as "unsent").

The Pilots say that flight 175 automatically acknowledged receipt. And they say that the Commission does not dispute this.

And you'd be surprised what a commercial plane can do (Egypt Air was approaching Mach 1 in a dive, and remained intact until they tried to pull up).
In terms of speed its (monster plane prototype, no particular model name needed) Mach 0.8 performance compares to the Mach 0.85 or better performance

A NATION CHALLENGED: THE TRADE CENTER CRASHES; First Tower to Fall Was Hit At Higher Speed, Study Finds
By ERIC LIPTON AND JAMES GLANZ
Researchers trying to explain why the World Trade Center's south tower fell first, though struck second, are focusing on new calculations showing that the passenger jet that hit the south tower had been flying as fast as 586 miles an hour, about 100 miles an hour faster than the other hijacked plane.
The speed of the two planes at impact has been painstakingly estimated using a mix of video, radar and even the recorded sounds of the planes passing overhead.
Two sets of estimates, by government and private scientists, have surfaced, but both show that the plane that hit the south tower at 9:02 a.m., United Airlines Flight 175, approached the trade center at extremely high speed, much faster than American Airlines Flight 11, which hit the north tower at 8:46 a.m.
In fact, the United plane was moving so fast that it was at risk of breaking up in midair as it made a final turn toward the south tower, traveling at a speed far exceeding the 767-200 design limit for that altitude..
Egypt Air 990 (EA990) is a 767 which was reported to have entered a dive and accelerated to a peak speed of .99 Mach at 22,000 feet. Boeing sets maximum operating speeds for the 767 as 360 Knots and .86 Mach. The reason for two airspeed limitations is due to air density at lower vs. higher altitudes. To understand equivalent dynamic pressures on an airframe of low vs. high altitude, there is an airspeed appropriately titled "Equivalent Airspeed" or EAS[1]. EAS is defined as the airspeed at sea level which produces the same dynamic pressure acting on the airframe as the true airspeed at high altitudes.[2]
Pilots For 9/11 Truth have calculated the Equivalent Airspeed for EA990 peak speed of .99 Mach at 22,000 feet as the equivalent dynamic effects of 425 knots at or near sea level. This airspeed is 65 knots over max operating for a 767, 85 knots less than the alleged United 175, and 5 knots less than the alleged American 11. Although it may be probable for the alleged American 11 to achieve such speed as 430 knots is only 5 knots over that of EA990 peak speed, It is impossible for the alleged United 175 to achieve the speeds reported by the NTSB using EA990 as a benchmark.

You do realize that cruise speeds aren't talking about at sea level right? They're talking about cruise at altitude, so Mach 0.8 is at 34,000 feet. That doesn't translate to 700 feet. And the 767-200 has a typical cruise speed of Mack 0.8, so how is the "monster plane" any better?
Zaphod58
So planes can't dive down, reach speeds faster than their normal operating range, level off and maintain those speeds for short times? What, once they reach that speed they just stop accelerating? Even if they dive down?

Because it's flying at 700 feet altitude, which would require a hardened structure and more powerful engines, and a performance capability that is well beyond that of the commercial Boeing 767-200, at that altitude, which it's simply not capable of, as outlined in the previous post.

This can be verified by anyone with the technical knowledge of the system - requires more research other than an ATS thread in the appropriate forum, and forgive me if I don't take your word for it, or that of the debunkers participating in that thread.

Absolute rubbish.
These "pilots" are misleading you and because you do not know what they are talking about you do not realise you are being lied to.
