Outdoor Festival Stages Falling Down

It seems that  not only the stock markets  are falling down these days but music stages as well. This summer three stages at music events have collapsed along with a video projection screen during storms. The latest incident occurred in Belgium ,at the Pukkelpop Festival. Previous to that  a stage toppled down in  the Indiana State Fair  where some people were killed and some got injured.,then  Ottawa Canada a 40- tonne stage fell down. So whats with all these tumbling downs? Clearly something is not going right and as much as we can blame the weather conditions there is enough technology that many manufacturers have to ensure that structures don't fall down and endanger people's lives while trying to enjoy some music events. So lets see some stricter inspection regulations and enforce some  high standards so construction becomes safe enough to avoid accidents in the future.
