Oliver Tree Killed After Mid‑Air Helicopter Collision Over Rio de Janeiro

Brazilian aviation investigators have begun on‑site evidence collection as authorities probe how the June 14 collision led to two crashes and a large fire at an electric‑vehicle yard.

Overview

  • Two helicopters collided and crashed over Recreio dos Bandeirantes in western Rio de Janeiro on Sunday, June 14, killing all six people aboard with no survivors.
  • Rio de Janeiro Civil Police identified the victims as Oliver Tree Nickell, Lucas Brito Chaves, Lucas Vignale, Gaspar Prim, and pilots Alexandre Souza and Charles Marsillac.
  • One helicopter struck the lot of a car dealership that stored electric vehicles, igniting a blaze that damaged roughly 20 cars and complicated the emergency response.
  • Brazil’s aviation accident authority CENIPA and the National Civil Aviation Agency (ANAC) have opened formal investigations and are preserving evidence and conducting forensic work; no cause has been released.
  • Tree was in Brazil on an active world tour and his death has prompted widespread tributes, halted his scheduled dates, and is likely to focus scrutiny on helicopter operations and safety procedures as investigators seek technical causes.
