Drones monitored Osamas compound months before May 2 assault

A US newspaper claimed that using unmanned planes designed to evade radar detection and operate at high altitudes, the agency conducted clandestine flights over the compound for months before the May 2 assault in an effort to capture high-resolution video that satellites could not provide. The aircraft allowed the CIA to glide undetected beyond the boundaries that Pakistan has long imposed on other US drones, including the Predators and Reapers that routinely carry out strikes near the border with Afghanistan.According to the paper, the US authorities were of the view that Pakistan would have done some secret arrangement for the security of the area as the country’s nuclear plant was also located in the area. But the advanced stealth technology went undetected on Pakistani radars.
