… in 1970, the Apollo 13 mission was crippled when a tank containing liquid oxygen burst. The Hollywood version of the crisis and its resolution (which starred Tom Hanks) is one of my all-time favourite movies. I often recommend it to kids who are thinking of studying engineering because it’s one of the best advertisements for the profession that I know of. It’s interesting also to think that if a similar crisis occurred today one of our strategies would be to ‘cloudsource’ the brainstorming.
