Washington, Nov 08: A commission investigating the Sept. 11 attacks voted to subpoena the pentagon for documents related to the activities of US air defences on the day of the terrorist hijackings. The independent commission yesterday said it was "especially dismayed" by incomplete document production on the part of the north American Aerospace Defence Command, or Norad, the part of the Defence Department responsible for protecting North American airspace.

The commission's broad investigation includes questions about how, and how quickly, the federal aviation administration notified US air defences about the hijacked planes in 2001. The commission's first subpoena, issued last month, was to the federal aviation administration.

The panel, formally called the national commission on terrorist attacks upon the United States, met privately yesterday about matters including production of documents it hasrequested from numerous government offices.
The panel, headed by former New Jersey Gov. Thomas H Kean, a Republican, has also encountered resistance from the White House in its efforts to review sensitive intelligence documents.
