In case folks in the USA missed it - there was a situation over the last few days, people were trapped in the tunnel under the English Channel:

"The trouble began Friday evening when five locomotives abruptly stopped on the tracks in the Channel Tunnel between London and Paris, trapping more than 2,000 passengers with no food, water or news about what was going on for up to 16 hours"

16 hours! Wow. A good reason to travel with water and food.
