When a single-engine plane crashed into an Upper East Side apartment building on Wednesday, Fox News Channel delivered early live video to its viewers from the crash site using a handheld mobile phone souped up with streaming video. Scott Wilder, a cameraman for the network, had been about 20 blocks away on another assignment when the crash occurred. Wilder ran uptown and reported live from the scene using a Palm Treo smartphone that uses the existing mobile network to transmit video to the Fox News control room. From there, Fox News sent it out live on TV to supplement other video being shot by local traffic helicopters.
