The Sentinel-1A radar satellite detected a slick in the eastern Mediterranean Sea – in the same area that EgyptAir flight MS804 disappeared early morning of 19 May 2016 on its way from Paris to Cairo. Sentinel-1A acquired this image later in the day at 16:00 GMT (18:00 CEST) in ‘extra-wide swath mode’ of 400 km with horizontal polarisation. ESA provided it to the relevant authorities to support the search operations. The 2 km-long slick is located at 33°32′ N / 29°13′ E – about 40 km southeast of the last known location of the aircraft. Although there is no guarantee that the slick is from the missing airplane, this information could be helpful for the search.
