Last week there was a 3 ac formation flying (what appeared to be) a route along the length of the Liffey, turning just past the docks and heading back up along the river.
Today, similar route but with a 4 ac formation.
All seems very tight and great to see. Just wondering, is it in preparation for something?
If not, can't help but wonder as to the wisdom of 'regular' tight formation flying over such a built up area.
