Aircraft descenced pretty fast though, quite a bit faster than I'm used to seeing on normal Gatwick inbounds.
If you suspect that you might be on fire you will get down as quick as possible then you have many more quick options open to you to chuck it on the ground.

I wouldn't!! Nobody should be criticised for the decision to get it down, and somewhere you have an engineering base would make sense if you can.
