An interesting new source has appeared : a recently published 9/11 Commission memo. According to this paper http://media.nara.gov/9-11/MFR/t-0148-911MFR-01098.pdf UA 175 sent an ACARS wheels-off message at 8:14 ("nose wheel strut extension"). This confirms what I'm saying: that the "wheels-off time" is triggered automatically by a mechanical sensor. But it doesn't confirm the time 8:23, instead, it matches the ATC/pilot transcript. Pretty odd, isn't it? What choices do we have now? Either (Scenario A) the 9/11 Commission is right in saying that the plane sent the wheels-off message 8:14 to United Airlines headquarters. In this case, it follows inevitably that - when United Airlines transmitted the ACARS data to the BTS, the 8:14 was somehow changed to 8:23 (I'd like to stress that the probability for such a change in an automated process is infinitesimal) AND - that Steven Miller, who demonstrably took off at 8:28, is telling fairy tales when he says that a Boeing 767 of United took off immediately before him *** (see footnote) AND - that the erroneous United/BTS transmission coincidentally matches Steven Miller's erroneous account. Or (Scenario B) the BTS database correctly reflects 8:23 as the point when UA 175 lifted off. In this case, it follows that the 8:14 in the 9/11 Commission memo is erroneous. Tracking back the information flow, we find that David Knerr, manager of United, provided Commissioner Miles Kara with the ACARS data. So - either Kerr submitted the wrong datum 8:14 to Kara OR - Kara (as the person responsible for the memo) got the correct datum 8:23, but for some reason it was substituted by 8:14 in the memo. I can't help; Scenario B looks much more realistic to me. How do you think? ***(I've already mentioned the theoretical possibility that Miller observed a non-domestic United 767 and falsely thought it was UA 175; non-domestic flights are not registered by the BTS. However, the daily number of non-domestic United 767's scheduled to depart from Logan was certainly small to very small, so this is also a coincidence of infinitesimal probability.) |
