Search area
On Rusian TV the resque team was talking that search area is 2-3 km wide.
So 30 square kilometers search area is more like 10x3 km .
Doesnt mean, that toddler was found 10 km away, my gues - from 6 to 10.
Again, on TV there was mentioned "next day we will search even more far". So, from 6 to 10 km is reasonable.
Also, on page 60 - there is the link to russian web site with passanger manifest. What was is not mention here, is story related to passengers on seats 30C and 30D. One has traumas related to falling, is "burnt not much", and recognizible by relatives, another one not indentified (or not found).
