- Retrieve contemporaneous ADS-B/flight plan, weather and camera pointing data Found in the CEFAA set: the DGAC radar replay (SRC-V99-146) shows Iberia IBE6830 (A346) climbing out near the helicopter's track at 16:48-16:53 UTC; the French analysis CEFAA commissioned (SRC-V99-147) concluded 'most probably a medium-haul twin jet airliner', which does not match an A340-600. No document in the set names the flight, and the crew record ATC saying there was no other traffic. (chunk G, 2026-11-12)
