Katie's going to be live in Kensal Green where it happened this morning - for something that lasted just a matter of moments, the damage has to be seen to be believed.
That's pretty much the bulk of the show - thanks to all of you who've sent in your pictures, we're running those along with ones our own crews have been filming - and we'll be asking Chrissie why it happened - and how significant it is.
We've got plenty of other news to pack in - AND Denzel Washington's been chatting to Steve.
I'm out of breath just thinking about it - do join us at 6, it's promising to be a great watch.
