Jag förstår inte hur man så lätt kan vifta undan de röster som höjs angående flygplanens hastighet, att etikettera dem som "truthpiloter" och kalla de som ifrågasätter dessa hastigheter för korkade känns ju inte så begåvat.
A Responsibility to Explain an Aeronautical Improbability

The airplane was UA175, a Boeing 767-200, shortly before crashing into World Trade Center Tower 2. Based on analysis of radar data, the National Transportation and Safety Board reported the groundspeed just before impact as 510 knots. This is well beyond the maximum operating velocity of 360 knots, and maximum dive velocity of 410 knots. The possibilities as I see them are: (1) this wasn’t a standard 767-200; (2) the radar data was compromised in some manner; (3) the NTSB analysis was erroneous; or (4) the 767 flew well beyond its flight envelope, was controllable, and managed to hit a relatively small target. Which organization has the greater responsibility for acknowledging the elephant in the room? The NTSB, NASA, Boeing, or the AIAA? Have engineers authored papers, but the AIAA or NASA won’t publish them? Or, does the ethical responsibility lie not with organizations, but with individual aeronautical engineers? Have engineers just looked the other way?
