(Reuters) - About 1,000 flights were cancelled or delayed in Dallas on Sunday night and more than 80,000 homes and businesses left without power early Monday, after a line of thunderstorms rolled across a northeastern swath of Texas before heading east.
A lightning strike at Dallas-Fort Worth International Airport about 7:40 p.m. knocked out communications between the control tower and planes on the ground, according to the Federal Aviation Administration. It also affected air traffic at nearby Dallas Love Field, which uses the same control tower.
