James Bennet reported in the New York Times that while "most" towns in the West Bank were quiet, some drivers in East Jerusalem were honking horns in celebration, he saw one man passing out celebratory candy.  Big crowds" celebrated in Nablus of Palestinians, chanting Beloved bin Laden, strike Tel Aviv! while Palestinian Authority personnel prevented photographers from taking pictures.  Annette Krüger Spitta of the ARD 's (German public broadcasting) TV magazine Panorama states that footage not aired shows that the street surrounding the celebration in Jerusalem is quiet. Furthermore, she states that a man in a white T-shirt incited the children and gathered people together for the shot. The Panorama report, dated September 20, 2001, quotes Communications Professor Martin Löffelholz explaining that in the images one sees jubilant Palestinian children and several adults but there is no indication that their pleasure is related to the attack. The woman seen cheering (Nawal Abdel Fatah) stated afterwards that she was offered cake if she celebrated on camera, and was frightened when she saw the pictures on television afterward.  
Bin Laden provided leadership and financial support for the plot, and was involved in selecting participants.  Bin Laden initially selected Nawaf al-Hazmi and Khalid al-Mihdhar , both experienced jihadists who had fought in Bosnia . Hazmi and Mihdhar arrived in the United States in mid-January 2000. In spring 2000, Hazmi and Mihdhar took flying lessons in San Diego, California , but both spoke little English, performed poorly with flying lessons, and eventually served as secondary – or "muscle" – hijackers.
