I answered exactly what was asked.
Why was an article written how the plane was identified and list the registration and serial numbers as evidence? They could have just asked all the experts here. You suppose?
Funny they didn't include any information about the FDR in identifying the plane. But then again that is never mentioned in anything written about the planes said to have hit the towers either.
How many plane parts were found on 9/11? Got a list?
As you well know - ATC, Radar, FDR, DNA, Witnesses etc etc etc identify the aircraft from 911.
In addition, plenty of plane parts were found on 911. I am sure that the FBI will have made a thorough investigation and may well have a list. Photographic evidence of plane parts are also available from many reliable sources.
Below is what you posted earlier. I have bolded the relevent parts for you to highlight your continued self debunking methods. You simply dont read or comprehend what you post because it answers your own question and 'debunks' your own arguement.
You sourced it. You posted it. Read it!
Quote from HI -
As an additional duty, aircraft maintenance officers are occasionally tasked as members of aircraft accident investigation boards and my personal experience was no exception. In 1989 I graduated from the Aircraft Mishap Investigation Course at the Institute of Safety and Systems Management at the University of Southern California. In addition to my direct participation as an aircraft accident investigator, I reviewed countless aircraft accident investigation reports for thoroughness and comprehensive conclusions for the Inspector General, Head Quarters Pacific Air Forces during the height of the Vietnam conflict.
In all my years of direct and indirect participation,
I never witnessed nor even heard of an aircraft loss, where the wreckage was accessible, that prevented investigators from finding enough hard evidence to positively identify the make, model and specific registration number of the aircraft and in most cases the precise cause of the accident. This is because every military and civilian passenger-carrying aircraft have many parts that are identified for the safety of flight. That is, if any of the parts were to fail at any time during a flight, the failure would likely result in catastrophic loss of aircraft and passengers. Consequently,
these parts are individually controlled by a distinctive serial number and tracked by a records section of the maintenance operation and by another section called plans and scheduling.
Following a certain number of flying hours, or, in the case of landing gears, a certain number of takeoff-and-landing cycles, these critical parts are required to be changed, overhauled or inspected by specialist mechanics. When these parts are installed,
their serial numbers are married to the aircraft registration numbers in the aircraft records and the plans and scheduling section will notify maintenance specialists when the parts must be replaced. If the parts are not replaced within the specified time or cycle limits, the airplane will normally be grounded until the maintenance action is completed. Most of these time-change parts, whether hydraulic flight surface actuators, pumps, landing gears, engines or engine components, are virtually indestructible.
It would be impossible for an ordinary fire resulting from an airplane crash to destroy or obliterate all of those critical time-change parts or their serial numbers. I repeat, impossible. - Colonel George Nelson
You 'debunked' yourself HI. Classic stuff. Keep it up. The TM will be so proud of you.
