I do wonder, if urthecast (in conjunction with NASA) could assist here. They have a live feed on the ISS (International Space Station) and this is soon to go live to the public, however it is currently live to them only while they fine tune the systems as they are going to be broadcasting this live on TV next weekend.
I digress. The ISS circles the earth every 90 minutes, and this camera can scan 90% of the earth in this time. Only parts it can't get are the poles. It is 1M resolution so can zoom in very close to earth, so much that it can see vehicles moving on the streets and pedestrians walking along the pavements.
If they have scanned this area (if they have this switched on), then perhaps this is data which could assist the NTSB and other SAR teams.
