Ms Deirdre O'Keeffe:

I thank the Deputy for the questions. Again, I am not in a position to give detail on these. However, there are people in the room who would be able to answer them. I will pass the question on night vision to Mr. Clonan. He might talk about fixed-wing aircraft at the same time. Then, Mr. Flaherty might deal with the Flight 999 question, if he can. We might go to Mr. Clonan first.
