Okay, so this has nothing to do with maintenance and reliability but it is a pretty fascinating set of shots. (And a remarkable feat of engineering)
I currently live and work in Dubai which is a phenomenal place. The most vibrant and growing place I have seen across all the countries I have visited. From my balcony I am able to see the construction of Burj Dubai, the worlds current tallest building.
Here are some shots from the 134th floor from there. Absolutely breathtaking views. The small buildings you can see are actually other high rise towers!
I actually flew over this thing a while ago. And as I was looking down I noticed that I could see (clearly) the cables on the tower cranes that were working there. That shook me a bit.
