Revisonist history by the author and perhaps Tur himself. Television stations were using helicopters in the 70s. As only one example, Francis Gary Powers was killed in August of 1977 flying for KNBC.
I was searching to see if anyone posted the story about Bob Tur now deciding that he’s a woman trapped in a man’s body but this is the only thread I found. Maybe it’s the horrible scenarios he’s witnessed that messed with his head and turned him into a woman that can no longer pilot a helicopter well. (I swear, he said the hormones he’s taking reset his brain somehow). What a putz.
