A company called DigitalGlobe spent the last few days uploading satellite images from the area the missing Malaysia Airlines flight disappeared in to their website Tomnod.
Why not crowdsource the search? See if you can find anything by combing through the images uploaded here.
The only problem? The site keeps crashing from everyone trying to spot either the plane or the wreckage of it. I just got through for the first time about five minutes ago, so if it doesn't load right away, try again. You get through eventually.
