Ex-NBC Nightly News anchor Tom Brokaw said he and his wife were “very, very fortunate” to escape a Wednesday morning blaze in their Upper East Side building. More than 100 firefighters were dispatched to the 12:30AM fire on the 14th floor of the landmark building — two floors above Brokaw’s apartment. Firefighters had the fire under control by 2:30AM. Six people, including five firefighters, received non-life-threatening injuries.
