Government Report on U.S. Aviation Warns of Security Holes
By ERIC LICHTBLAU

WASHINGTON, March 13 - Despite a huge investment in security, the
American aviation system remains vulnerable to attack by Al Qaeda and
other jihadist terrorist groups, with noncommercial planes and
helicopters offering terrorists particularly tempting targets, a
confidential government report concludes.


Intelligence indicates that Al Qaeda may have discussed plans to
hijack chartered planes, helicopters and other general aviation
aircraft for attacks because they are less well-guarded than
commercial airliners, according to a previously undisclosed 24-page
special assessment on aviation security by the Federal Bureau of
Investigation and the Department of Homeland Security two weeks ago.

But commercial airliners are also "likely to remain a target and a
platform for terrorists," the report says, and members of Al Qaeda
appear determined to study and test new American security measures to
"uncover weaknesses."

The assessment comes as the Bush administration, with a new
intelligence structure and many new counterterrorism leaders in place,
is taking stock of terrorists' capabilities and of the country's
ability to defend itself.
