LAS VEGAS (AP) — Two single-engine aircraft banked from opposite directions toward the same runway in North Las Vegas last month, before crashing and killing all four people aboard, a preliminary report by federal crash investigators showed Friday. A National Transportation Safety Board diagram of the July 17 crash clearly shows the paths of a Piper PA-46 from Coeur d’Alene, Idaho, with two people aboard ,and a Cessna 172 with an instructor and student pilot, come together at North Las Vegas Airport. The Clark County coroner found the two people on the Piper — Donald Stuart Goldberg, 82, and Carol Ann Scanlon, 76 — died of trauma injuries before their aircraft wreckage burned. Their deaths were ruled accidental. Rulings on the causes of deaths are pending for Cessna student pilot Zachary Rainey, 46, of North Las Vegas, and instructor Anthony Chiaramonti, 40, of Las Vegas.
