VOICED: Navigating the volcanic ash cloud safely

The video discusses the impact of volcanic ash on air travel, focusing on safety concerns and economic implications. British aviation authorities have kept airspace closed due to safety risks, while French authorities have reopened theirs after successful tests. The ash, composed of glass particles, poses a threat to jet engines by clogging cooling systems. Despite economic pressures, safety remains the priority, with air traffic reopening only in monitored areas.
