Excavator vs Smokestack

Not sure what exactly is going on here but this excavator appears to be helping demolish an old smokestack. Apparently the workers used TNT the first time to bring the smokestack down but that failed, so they decided to bring in an excavator to finish the job. As you can see in the video, the excavator is digging away at the side of the smokestack, when suddenly things take an unexpected turn.

Out of no where the smokestack beings to collapse, which is scary enough but then to make matters worse, the entire smokestack falls in the same direction as the excavator covering it in bricks. You can hear the crowd nearby gasping in shock as this giant structure falls on top of this excavator and the guy behind the wheel. Fortunately the driver appeared to be unharmed, which is extremely lucky considering this massive structure just fell on top of him. It definitely could’ve been a lot worse but still we gotta ask, why was this a good idea? This whole situation looked unsafe from the beginning. What do you think about this?
