This site has grown significantly beyond any of my expectations. My initial intent was to provide a source of information for the Penn State AE community. Over the months since September 11, 2001 I have found that many people have found it useful. I will continue to update the site as new information is located. Please send any information you have to Prof. Louis Geschwindner at

September 14 was a special day of prayer, remembrance and expression of patriotism. As a reminder of these events, you can check out the listing that was previously on this page.

The major activities currently taking place are the NIST Investigation of the WTC and the release of the six plans for Ground Zero from the Lower Manhattan Development Corporation.
