Two firefighting helicopters collide near Athens during wildfire operations

Wildfire pressure across Greece

The crash comes as Greece continues to battle widespread wildfires that have strained the country's firefighting capacity. Wildfires are a recurring threat in Greece during the summer months, when high temperatures, dry vegetation and strong winds can rapidly escalate blazes into large, fast-moving fronts. Aerial resources, including water-dropping helicopters and fixed-wing aircraft, are routinely deployed alongside ground crews to contain the fires before they reach inhabited areas.

The collision underscores the operational risks that aerial firefighting crews face when multiple aircraft operate in the same airspace above an active fire. Coordinating low-level flight paths in smoky, turbulent conditions is a complex task, and accidents, while rare, have occurred in other fire seasons in southern Europe. Authorities typically open an investigation after such incidents to determine the causes and to inform future safety protocols.

Risks of low-level aerial firefighting

ERT, the Greek public broadcaster, was the first to report the collision on Sunday. The broadcaster did not provide additional identifying details about the aircraft or the operators involved. Greek emergency services were reported to be coordinating the search and rescue effort in the area near the village west of Athens.

Investigation and official response

The wider wildfire situation in Greece has drawn international attention in recent summers, with the European Union mobilising support through its civil protection mechanism. Countries including Spain, Canada, the United States and Britain have previously contributed aircraft, ground crews or coordination support during severe fire seasons in the Mediterranean. It was not immediately clear from the verified reporting whether any foreign-assigned aircraft were involved in Sunday's collision.

The village near which the wreckage was reported lies in a rural, forested zone west of Athens, an area that has seen major wildfires in past years, including the deadly 2018 fire that struck the coastal town of Mati and killed more than 100 people. The memory of that disaster remains vivid for residents and emergency planners, and it shapes the urgency of the response to any new blaze in the region.

Greek authorities have not yet publicly identified the crew members involved or confirmed their condition. Families of the personnel are typically notified before any official identification is released. The investigation into the cause of the collision is expected to be led by Greek aviation safety authorities in coordination with the relevant fire services.

Broader regional context

Residents in nearby villages were urged to follow guidance from local authorities and the fire service, including potential evacuation orders if the wildfire approached inhabited areas. Smoke from wildfires burning across the broader region has periodically affected air quality in parts of Attica, the peninsula that includes Athens.

The search and rescue operation was reported to be ongoing at the time of ERT's initial report. Further updates from Greek officials, including the fire service and the ministry responsible for civil protection, are expected as the situation develops.

The collision is the latest reminder of the dangers faced by frontline emergency workers during the Mediterranean fire season, which forecasters have warned is lengthening and intensifying as a result of climate change.
