Hold onto your boxers.

According to the National Transportation Safety Board (NTSB.GOV), Flight 175 originated not at Logan airport. No. But at the BOSTON HELIPORT, CODE 1MA3.

The code for Logan is "BOS," not "1MA3." Check list:

I did not personally discover this info. It was posted several places including Pilots for 911 Truth. Another poster suggested that the heliport was actually closed at that time.

However, I did the obvious thing, and looked into what they said about Flight 11, also supposedly out of Boston.
