The issue is a lot of new skyscrapers built with highly flammable cladding materials, we have the same problem in australia.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!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.
