Jet coaster

I watched the program on the recent development of jet coasters in U.S. and other countries in Discovery Channel on May 4 and the accident in Osaka on May 5 was really a shock. This could be analysed quite a different standpoints, namely, first how old the jet coaster in Osaka was, second, how careful the management of the company that operated it in making sure if the system worked without any problem or not, and third how far the gap between the high-tech jet coaster and the others was.

I would like to add that I am too old to get on a jet coaster now. If it was 20 years ago, things would have been different.
