But even better, Earth now has a clock icon to accesses data sets from
different eras... so you can see what City Airport looked like before and
after the DLR was built.

And if you look at Rwy 09L at Heathrow and take it to Early 2004 you can see
that lovely imaging error which shows the same Air France aircraft if four
different places.
