Incident at Heathrow

[kenjaDROP]

To quote AAIB Bulletin S3/2013 SPECIAL:

Safety Recommendation 2013-011
It is recommended that Airbus formally notifies operators
of A320-family aircraft of the fan cowl door loss event
on A319 G-EUOE on 24 May 2013, and reiterates the
importance of verifying that the fan cowl doors are
latched prior to flight by visually checking the position
of the latches.

- to refer to my earlier post, what bl**dy good does it do in "visually checking the position of the latches.". I remain pretty damn sure that the latches can be closed/stowed/pushed home/flush, not hooked on, with the cowls still 'dangling'!
The only tell-tale then is the gap around the actual cowls. Am I right?
If so, why the AAIB recommendation to look for latch positions?!!!
