Guys,
Without reference to the above incident may I suggest that those of you that are not aware of the Eurocontrol ACAS Bulletins take a look at them here
https://www.eurocontrol.int/search?k...blication_date
They are very good reading and start with No 1. They are published periodically so there are quite a few now and you will not read them all in one sitting but they are really worth reading for all pilots on both sides of the pond.
