The point is go-arounds are the safe option, air trafic controllers may be right 99% of the time and are our best friends, the 1% is up to the flight crew so they will always have the final say. Gatwick only has 2.5 miles approach separation so only about 55 seconds from 50 feet to getting off the runway, but in this case the A330-200 was taking off so the crew did have time to make the best decision, upsetting passengers and making the news is a small price to pay. In our operations manual it says a professional pilot does a go-around. History shows that many more pilots should have done this.
