A BBC examination of summer disruption describes how storms, crowded airspace and limited diversion capacity can combine. Experts differ on the scale of the worst-case safety risk. The practical story is how aviation builds enough resilience for a weather event that affects several airports at once.
Weather does not need to close every runway to overwhelm a tightly connected flight network.
What is likely to happen next
For travel decisions, check current airline and airport updates rather than this background analysis. At an industry level, watch diversion planning, weather forecasting and recovery performance during widespread disruption. Expert disagreement should remain visible as those risks are assessed.
This is a conditional editorial assessment, not a measured probability or a guaranteed outcome.
