When Jonathan Walczak was 15, a newspaper article about a disposable camera found in the rubble of the World Trade Center sparked a lifelong obsession. The FBI had developed film from the camera, revealing images taken inside one of the towers during the 9/11 attacks. Walczak kept the clipping for years, later using his reporting skills to file Freedom of Information Act requests in his early 20s to obtain the photos.

He insists he is not a conspiracy theorist but a 'Sept. 11 completist,' driven to verify and preserve unseen footage from that day. Through his podcast 'Missing on 9/11,' he has documented verified photos from various tower floors and connected with a community of amateur archivists on Reddit who analyze images to reconstruct the events. Recent discoveries, including a forgotten camcorder video and footage of office equipment falling from shattered windows, have energized the group.

Yet for Walczak, the disposable camera remains the ultimate missing piece—the 'Zapruder film of 9/11'—a chilling chronicle of a jumper’s final moments that he believes still exists in FBI archives.
