Noted 9/11 research Dr. Frank Legge has published a revised version of his paper with additional notes and discussion, “What Hit the Pentagon?” The paper is available at the Journal of 9/11 Studies:

His first version of the paper generated a great deal of discussion about this important issue. In presenting this revision, Dr. Legge notes:

“This version has been prepared to take into account a number of issues raised by critics and defenders of the original paper. Discussion of the implications of accepting or rejecting the official position that a 757 hit the Pentagon has been expanded and clarified. I am very grateful for the help provided. All significant alterations have been identified and discussed in footnotes.”

No doubt this revised version will encourage further discussion of what hit the Pentagon, and perhaps more importantly, a renewed push to obtain release of withheld video footage that will show unequivocally what hit the Pentagon – and a renewed interest in the whistleblower testimony of Secretary of Transportation (at the time) Norman Mineta.
