York City area television stations and several radio stations, were destroyed when two hijacked airplanes crashed into and destroyed the World Trade Center. WNBC broadcast engineer Bill Steckman died in the attack, along with Don DiFranco of WABC-TV; Gerard Copolla of WNET; Steve Jacobson of WPIX; and Bob Pattison and Isaias Rivera of WCBS-TV. In the immediate aftermath, the station temporarily fed its signal to three UHF stations that were still broadcasting (PBS member station WLIW and independent stations WMBC-TV and W26CE). After resuming over-the-air transmissions, the station broadcast from the former transmitter site of Channel 68 in West Orange, New Jersey. Since 2005, WNBC has broadcast its signal from the Empire State Building in midtown Manhattan, returning to the original transmitter site used from the 1930s to the 1970s. On May 9, 2017, it was announced that WNBC would return broadcasting from lower Manhattan at One World Trade Center by the end of the year. In 2004, WNBC served as the model station for NBC Weather Plus, a 24-hour digital weather channel that aired on its second digital subchannel (4.2) and several local cable systems; other NBC-owned stations launched their own Weather Plus channels in 2005, although Weather Plus was discontinued at the end of 2008. WNBC discontinued regular programming on its analog signal, over VHF channel 4, at 12:30 p.m. on June 12, 2009, as part of the federally mandated transition from analog to digital television. The station's digital signal remained on its transition period UHF channel 28, using Program and System Information Protocol to display WNBC's virtual channel as 4 on digital television receivers. As part of the SAFER Act, WNBC kept its analog signal on the air until June 26 to inform viewers of the digital television transition. During this time, the station would participate in the "Analog Nightlight" program for two weeks, with a looped video in English and Spanish explaining how to switch to digital reception. In February 2015, WNBC and the other NBC-owned stations offered live, web-based streaming of programming to subscribers of participating cable and satellite television providers, as provided through the TV Everywhere Mobile Apps. On March 15, 2016, NBCUniversal pulled the signals of WNBC and WNJU along with co-owned cable channels USA Network, Bravo, Syfy, MSNBC and CNBC from Dish Network's lineup in the New York metropolitan area as a result of a dispute between NBC and Dish; despite that,
