Pedrógão Grande fire, Portugal (2017)
A wildfire tore through central Portugal, killing 66 people, many trapped in their cars on a single road. It was the deadliest fire disaster in the country's history and overwhelmed national firefighting resources.
Portugal drew emergency aid from Spain and France and overhauled its forest and warning systems.
The scale of the loss helped push the EU to create rescEU in 2019, a standing reserve of firefighting aircraft it owns or funds directly.
It is the disaster that convinced Europe a shared reserve was worth building. The 2026 season is the biggest real test of that idea.
