The claims list I looked at, is in the fourth band, regarding the date it self, Mombeek has no entry for that day in band 3, which it should be chronlologically.
Anyway, this has to be a massive surprise attack, and kind of chaos, Ehrler claimed four down planes this day, so it must have been kind of the fox in the hen house, and records probably would indicate that.
This is your reference right?
