Helicopters can conjure all kinds of images. Think of the Los Angeles news chopper over the slow-speed police chase of O.J. Simpson and his white Ford Bronco back in 1994, before Simpson was arrested and charged with murdering his ex-wife Nicole Brown Simpson and her friend, Ron Goldman. (That white Bronco is now in a Tennessee crime museum.) Others might equally hearken back to 1980s’ TV shows — think “Magnum P.I.” or “Airwolf.”
