The refinery that I built a model of for my NTRAK modules was closed down a while back. The property will be redeveloped but first they had to demolish many of the old industrial buildings. The big red brick Char Filter House will be renovated and turned into a residential and retail property. This morning they set charges to bring down the metal buildings around it.
The first building went down without a problem but the charges under the second one failed to go. After they reset everything they tried again an hour later. The charges all went off but the building just leaned a little and stopped. Finally about 20 minutes later it suddenly collapsed. My camera was turned off so I missed the second building toppling over.
