Helicopter Collision Kills Two as Greek Wildfires Rage Near Athens
Two crew members died on Sunday when two firefighting helicopters collided near Psatha in Greece's Attica region, as crews struggled to contain a wildfire that has destroyed more than 100 homes northwest of Athens. Greece's fire service said the two people killed on one aircraft were a Greek and a Danish national; the two crew members on the other helicopter, one Greek and one British, survived. An investigation into the cause of the collision has begun.
Video posted on the Forecast Weather Greece Facebook page, which Reuters has not verified, appeared to show the two helicopters converging at low altitude before the main rotor of the lower aircraft struck the underside of the other; the lower helicopter then crashed in flames and the second dumped its water load and flew away. Separately, the eKathimerini website reported that investigators believe the fire that started in Boeotia and spread into Attica may have been sparked by conductors on a private network carrying electricity from wind turbines to the main grid. Two Greek nationals have been arrested on suspicion of negligence and a third suspect remains at large, the report said.
The collision came as Europe contended with fires on several fronts following a summer of record heatwaves and scarce rainfall, conditions scientists say are worsened by climate change. In Greece, gale-force winds that had pushed a blaze around Porto Germeno on the Gulf of Corinth subsided, but flames crossed a mountain to the south and reached the settlement of Veniza and a military firing range, setting off unexploded ordnance. Emergency crews focused on stopping the fire from advancing on Megara, a town of about 30,000 people, and evacuation alerts were issued for settlements in western Attica, including an industrial estate. Settlements on the island of Kefalonia were also evacuated overnight after a new fire broke out in the south. Prime Minister Kyriakos Mitsotakis said there were moments when the "force of nature" and the intensity of the weather exceed all human planning and operational capability.
In France, a fire in the Var region changed course after a shift in the wind and surged into difficult-to-access forest, while a separate blaze beside a highway near Carcassonne, apparently caused by a burning vehicle, closed the road and forced the evacuation of a nearby animal park. In Spain, large wildfires that have burned tens of thousands of hectares were mostly under control, though some areas saw reignitions and about 800 people evacuated by a forest blaze in Caceres remained confined to their homes. Meanwhile, drought has pushed the Danube to its lowest recorded levels in Hungary, Serbia and Romania. Hungary's Prime Minister Peter Magyar warned of a "critical five days" ahead as the river's decline forced the country's sole nuclear power plant to shut down for the first time in more than four decades, with a new heatwave looming. Serbia's energy minister said the Danube's lowest level since 1985 had cut the country's biggest hydropower plant to 20% of normal daily output.
Why the Drought, Not Just the Flames, Demands Europe's Attention
The fatalities and evacuations are the immediate story, but the more durable signal for business readers is drought moving into Europe's energy and logistics systems. Two pressures are compounding at once: fire-related disruption that is nearly impossible to model, and water scarcity that is now directly constraining power generation.
Why the Psatha collision will sharpen scrutiny of aerial firefighting
The collision occurred with multiple aircraft working one blaze in smoke, gale-force wind and rugged terrain. The unverified video appears to show the helicopters crossing paths at low altitude, which raises questions about how airspace is managed over an active fire. Greece's fire service has opened an investigation, and the deaths of the two crew members — a Greek and a Danish national — will likely broaden that scrutiny across Europe, where firefighting fleets are being used intensely in a succession of dry summers. Mitsotakis's remark that the force of nature can exceed operational capability is a candid acknowledgment that simultaneous fires can stretch resources thin.
Hungary's nuclear shutdown turns drought into a power-supply event
The Danube's fall to its lowest recorded level in Hungary forced the country's sole nuclear power plant to shut for the first time in more than four decades. That is a notable shift: a baseload plant going offline because of water, not mechanical failure, shows hydrological stress moving from agriculture into the electricity system. Magyar has flagged a critical five-day window with another heatwave approaching — a period in which cooling demand typically rises even as generation capacity is reduced. Serbia's biggest hydropower plant, running at 20% of normal output, tightens the regional picture further. How the gap will be covered — through imports, thermal reserves or demand measures — has not been spelled out.
Low water levels are a logistics and tourism problem on the Danube
Record-low river levels have already disrupted shipping and tourism in Hungary and triggered water-use restrictions in more than 100 cities and villages. Barges on the Danube carry bulk goods along one of Europe's main inland waterways, and low water forces lighter loads and longer transit times. With levels in Serbia at their lowest since 1985, the constraint is regional rather than local, and the effect will show up in transport costs and delivery schedules even if the river itself remains navigable.
A pattern, not a one-off summer
Scientists quoted in reporting on this year's fires tie the record heat and scarce rain to climate change. Each summer of fire emergencies in Greece, France, Spain and elsewhere is a data point in that pattern, and each drought event stress-tests infrastructure designed for an older climate — firefighting fleets, power plants that depend on river water, and inland navigation systems. The costs of adapting that infrastructure are becoming a recurring line in European budgets rather than a rare emergency item.
What to Track as Heat and Low Water Levels Persist
For businesses and households exposed to Europe's heat and drought, the next few days will be decisive. Watch these specific threads:
- Hungary's nuclear restart: Prime Minister Magyar has defined a critical five-day window; a restart date and any contingency generation plans will clarify the impact on regional power prices.
- Danube navigation: with river levels at record lows in Hungary and their lowest since 1985 in Serbia, shippers should factor in reduced barge loads and longer transit times.
- Fire status in western Attica: evacuation alerts for settlements and an industrial estate near Megara remain in force; companies with operations or supply chains in the area should track them.
- Water-use restrictions: limits already cover more than 100 Hungarian cities and villages, and the approaching heatwave could extend them.
