Good little walker! Although in practical terms it’s only about 250m per hour and even if he managed getting some sleep for half of the time he was missing, it’s still only 1/2 a km per hour.
I love happy endings and I’m so glad the search parameters were open... There was a sad case in the US in the last couple of years where a 2 year old wandered off but the search quadrant was kept to about 1/2 a mile. Unfortunately he was found dead 2 miles away. (Noah Chamberlin

I hope this case will set a good precedent for search teams to set very real and wide-spanning parameters for little lost feet!
