No the formation was football shaped. Another cause of a hole in the
pattern
could be a bomb load going out taking improperly installed arming wires
with
them. But that was rare.

Were all the bombs released at the same time to form a football pattern on
the ground, or did each bomber released the bombs over the target? Was the
football shape chosen to minimize crosswind condition at the target? In
that case, bomb trajectory can drift sideways and the main axis of football
will be off the target.
