Render planes first

[jidanni]

I have a bookmark
http://www.flightradar24.com/24.24,120.88/12
that I press oh, once a day, every time a funny sounding plane
flies overhead. Alas, one needs to wait for the entire
web page to be rendered, of which the last thing is the planes.
It would be nice if the planes were rendered first.

Planes are rendered on the Google map using Google maps API, so it's a bit hard to get them rendered before the map.
