The NYT reports
The terrorists who struck this city last month stunned authorities not only with their use of sophisticated weaponry but also with their comfort with modern technology.
The terrorists navigated across the Arabian Sea to Mumbai from Karachi, Pakistan, with the help of a global positioning system handset. While under way, they communicated using a satellite phone with those in Pakistan believed to have coordinated the attacks. They recognized their targets and knew the most direct routes to reach them in part because they had studied satellite photos from Google Earth.
