The issue is a lot of new skyscrapers built with highly flammable cladding materials, we have the same problem in australia.That is just horrible, reminds me of the Grenfell Tower fire that occurred in England a few years ago. Such external materials must be banned everywhere.Watch out! In about 20 minutes it’s going to free-fall into its own footprint and shatter into a million pieces and leave a glowing crater that can be seen from space for weeks! Happens all the time!
