If you thought Wednesday evening's storm was scary from the ground, just imagine the the horror people in the air were going through. Passengers on board planes travelling from Reykjavik, Edinburgh and Prague were reportedly caught up in the storm and happened to be mid-air as lightning struck.
Observers on the ground captured terrifying images of lightning bolts appearing to collide with planes.
This video, taken as a flight soared above West London at 8:10 pm, shows the lightning strike in dramatic detail.
Passengers were quick to take to Twitter and share their mid-air nightmare.
British Airways flight BA857 from Prague was caught up in the commotion.
The airline told the Press Association: "The flight landed safely, and will undergo inspection before it returns to service. The safety of our customers and crew is always our top priority. Lightning strikes are fairly common, and aircraft are designed to cope with them."
