The search grids, June 1 through June 5
The search grid on June 6, when the first wreckage and bodies from the plane were spotted.
Unfortunately, in retrospect, the searches June1-5 concentrated on areas to the right of the track, and south of the last reported position.
In the June 1-5 image, the June 1 search grid was the narrow rectangular box from the last reported position almost to Tasil. The June 2nd search grids were mainly the two rectangular boxes, almost perpendicular to the June 1 search box, and to the right of the track.
I believe the circle in the June 6 image was not a search grid. but only an indicator of the distance from the last reported position and the debris sightings.
