The image at left above was taken by NYPD helo pilot Detective Greg Semendinger on September 11, 2001, maybe there is at least one person visible at the corner out of the smoke, the 911 Tourist Guy remains unaccounted for and sometimes it looks like it could be him, whoever it was must have died cursing the NYPD for not attempting his or her rescue.
By Scot J. Paltrow and Queena Sook Kim, Staff Reporters @ The Wall Street Journal, October 23, 2001. Within minutes of the first air strike on the World Trade Center September 11, 2001, an NYPD Bell 412 helicopter with a 250 foot hoist and a three man crew trained for rooftop rescues, piloted by Detective Greg Semendinger arrived at the WTC.
In 1993 after a bomb exploded in the WTC basement garage sending thick smoke up through the stairwells, Semendinger had lowered two men to the roof of the same North Tower, who removed antennas to clear a landing area from which twenty eight workers were airlifted to safety.
