Greek inquiry examines 15-minute coordination gap in fatal Psatha helicopter crash

Investigation into the Psatha collision

Greek authorities are examining the operational conditions surrounding the mid-air collision between two firefighting helicopters in Psatha on 2 August 2026. The fatal accident occurred during suppression efforts against a large wildfire that spread from Boeotia to West Attica, causing the deaths of two individuals. While one helicopter was destroyed, the second aircraft involved in the collision maintained flight control and completed an emergency landing without further casualties. The Directorate for Combating Organized Crime has taken charge of the preliminary inquiry to determine the procedural and operational causes of the crash. Investigators have taken more than 15 formal depositions, gathering evidence from fire service officers, operational personnel, area residents, and the surviving crew.

Surviving crew testimonies

Depositions from the two survivors, a British captain and a Greek interpreter who occupied the second aircraft, provide the first direct accounts of the incident. The crew members told investigators that they lacked visual contact with the intersecting aircraft and did not see it approach before the impact. When the rotor blades collided, the occupants believed their aircraft had become entangled in electrical transmission infrastructure rather than striking another helicopter.

We had no visual contact. We thought we hit power cables.

The survivors explained that their aircraft operated as the second unit in a tactical formation behind a lead helicopter that directed the group. They stated that the aerial coordinator issued instructions to hold position until the lead helicopter completed its water drop, then release their load immediately afterward. The crew stated during questioning that they were unaware of a third helicopter operating in the same sector, though they overheard radio traffic from a third crew indicating an approach to their position.

Airspace coordination transfer

Investigators have placed particular focus on a 15-minute command gap that occurred immediately before the collision over the Psatha front. Air traffic in the Psatha operating sector was initially directed from the ground by a high-ranking Fire Service officer who maintained direct visual observation of all participating aircraft. Approximately 15 minutes before the crash, that officer left the immediate sector to respond to a wildfire flare-up in another location. Under standard Fire Service operational protocols, tactical control of the airspace transferred automatically to the designated aerial coordinator using the callsign Floga. The coordinating aircraft was operating above Vilia over a separate portion of the fire perimeter, leaving it without a direct line of sight to the airspace above Psatha.

Audio analysis and expert review

The inquiry is examining recorded audio transmissions between the command center, coordinating officers, and individual flight crews. Judicial authorities seek to verify what orders were transmitted to the pilots and whether adequate warnings were issued regarding traffic separation. Because the communication tapes contain technical aviation jargon and specialized tactical callsigns, the evaluation is being conducted by three aviation navigation experts appointed by the prosecution rather than standard police investigators. The resulting communications report will be integrated into the case dossier alongside technical findings from court-appointed experts and party representatives. Judicial officials will summon the ground and aerial mission coordinators to provide formal testimony as the final phase of the preliminary inquiry.
