My estimation of holes sizes (20Mb):

1. I took the picture of MH17 and measured the red stripe size and the fuselage size in pixels. So i got the factor to infer the red stripe size in mm (by multiplying on the fuselage size 6200mm). That is 342 mm.
2. I found a 400mm ruler image and scaled it to match the size of the red stripe
on the famous debris image (in a particular layer).
3. I copied the ruler's layer to apply it throughout the debris image close to holes.
