Kyodo Tsushin News took the video on February 26, 2012 from a helicopter. To view the video, go here.
Other than the tarp-covered Reactor 1 building and cranes to remove large debris, it looks the same as, say 6 months ago. From this angle, the Reactor 4 building looks just like it was on the day "a fire broke out" on March 15, 2011. In that sense, the plant is very "stable" - hardly anything changed after nearly a year.

NHK has their video here.
