Would London survive the impact of a blue whale dropped from space?

This question has been bothering me for some time. If a whale (specifically, the Balaenoptera musculus or blue whale, at 180 tonnes) was dropped from space (the outer limit of the Earth’s atmosphere), what impact would it have on a city, compared to the Hoba meteorite in Namibia, which weighs 60 tonnes? Would, say, London survive the whale?
