Introduction

On the morning of 11 September 2001, 19 terrorists from the Islamist extreme group al Qaeda hijacked four commercial aircraft and crashed two of them into the North and South Towers of the World Trade Center complex in New York City. A third plane crashed into the Pentagon in Arlington, Virginia. After learning about the other attacks, passengers on the fourth hijacked plane, Flight 93, fought back, and the plane was crashed into an empty field in western Pennsylvania about 20 minutes by air from Washington, D.C. The Twin Towers ultimately collapsed, due to the damage from the impacts and subsequent fires. Nearly 3,000 people were killed from 93 different countries. Most of the fatalities were from the attacks on the World Trade Center. The Pentagon lost 184 civilians and servicemembers and 40 people were killed on Flight 93. It was the worst attack on American soil since the Japanese attacked Pearl Harbor in 1941.

After the Taliban refused to turn over the mastermind of the attacks, Osama Bin Laden, Operation Enduring Freedom officially began 7 October 2001 with American and British bombing strikes against al Qaeda and Taliban forces in Afghanistan. Initially, the Taliban was removed from power and al Qaeda was seriously crippled, but allied forces continually dealt with a stubborn Taliban insurgency, infrastructure rebuilding, and corruption among the Afghan National Army, Afghan National Police, and Afghan Border Police. Bin Laden would go into hiding for nearly 10 years.

On 2 May 2011, U.S. Navy SEALs launched a nighttime raid on Bin Laden’s compound in Abbottabad, Pakistan, killing the al Qaeda leader. Operation Enduring Freedom officially ended 28 December 2014, although coalition forces remained on the ground to assist with training Afghan security forces. American troops departed Afghanistan in August 2021.

Navy Combat Documentation Detachment 206 Pentagon 9/11 Oral Histories

In the immediate aftermath of the attacks on 11 September, the Department of Defense and all of the branches of the Armed Forces began efforts to document the attacks. The Naval Historical Center (the predecessor of NHHC) activated its reserve unit, Navy Combat Documentation Detachment 206 (DET 206) to assist in the documentation efforts. Over the next ten months, DET 206 reservists and NHC Historians interviewed hundreds of individuals who were in the Pentagon on the day of the attack or were directly involved in the Navy’s response and the work that followed. The Navy Archives has received permission to release a portion of the oral histories to the public for the first time since they were recorded. The oral histories that have been authorized for release can be found at the link above.

Heat Damage

Heat damage from the fire after the attack on the Pentagon caused thermoplastic components to melt, warp, and keys to separate from the base of the laptop. Additionally, heat formed an impression of a security strap on the exterior of the laptop and cracked the screen.
