terminal-5

Your mission

Fill out with the number of bags that made it onto each belt.

today's brief

March 27, 2008. Terminal 5 opens at Heathrow with a baggage system that had been rehearsed on ten million bags, and it falls over on the first morning. Staff cannot find the car park. Handlers cannot log in. Bags pile up because the software has nowhere to put the ones it cannot place, and by the end of the week 500 flights are cancelled with 23,000 bags stranded. Count what actually reached each belt.
