Sean O'Flaherty, WTMJ (and Scripps') longest-tenured employee, passed away on Friday, at the age of 74. He had been with the station for 53 years, holding the position of Newsroom Operations Manager for the last several decades.

Sean had started out as a reporter at the station, some of his packages are available online on UW Milwaukee's digital archives of WTMJ's film collection. One package that's not on there is coverage of a failed hot air balloon race in 1975, the crew of which coincidentally included the balloon pilot from WITI's "Look up to TV6" promo from a few years prior.
A sad loss not only for WTMJ, but the entire Milwaukee market. Sean also moonlit (literally) as the station's weekend overnight photographer, and was well known at the other stations in town, even by those who never worked at WTMJ.
