No what Kate describes is physically correct. The air speed increased as the gap decreases i.e "as I closed it to about here".
After entering the apartment and stating that she probably wouldn't have checked inside the children's bedroom had the door not 'suddenly slammed' as she went to return it to 'the position they'd left it in'. She THEN goes on to state she found the window and shutters open, cold, icy fear, no please no etc ad nauseum..... She even says she checked if the patio door WAS shut - it was.
1-An exterior door to be open
2-An interior door to be open. PLUS:
3-An interior window OR another exterior door to be open.
In k mccann account only' only 2 of the 3 conditions apply.
Therefore, however windy it was, the door should have slammed the moment k mccann entered the patio, not a minute or so later.
Doesn't it require the suction of a through-draft to pull a door shut.
I have NEVER known a door to slam in the circumstances she described.
