The weather that day was pretty poor. As previously mentioned, I walked out with the crew to take part in a 3 ship Puma trg sortie on the NE Antrim coast. Around the Cushendall area, the cloudbase was about 3-500' Amsl and we could see the scottish coastline in excellent visibility underneath that. We heard Scottish trying to call the Chinook on 243.0 but thought it wasnt answered because they were too low. Even though the cloud was so bad, we managed to get some useful training done underneath. The rest is history.
