the Glasgow fire reminds me of my second date with my now gf. we were in Dundee city centre, as you do, and this... what looked like fog came rolling down the street. We noticed it and decided to follow once it became clear it was smoke...
behind the shopping centre and next to the old cemetery, the Howff, there was this derelict old multi-floor department store. It'd been closed for a while even before I moved to Dundee, but it was a beautiful thing even dilapidated.
at first it was only smouldering, and you could see a bit of flame in the windows. Before too long though, the whole thing was up in flames, and you could see and hear floors falling into the inferno. It was so hot you could feel the heat from the other side of the Howff (we stayed well away from the actual building), and embers started raining down like dirty grey snowflakes.
We left once the crowd got too big, but I remember brushing bits of building off my shoulders, and the next few days the streets were littered with ash.
The only thing left of the building now is a wooden board sign for the car park it had, and the metal lettering above the entrance, which had warped with the heat. it's now in the McManus (the museum in Dundee), and it's surreal to stand and look at it there now knowing we watched the place burn.
Apparently you could see the glow on the other side of the Tay, in northern Fife.
