"The only way I can stay on top of it is to find out who they are and what they are, they come across that fast," he said yesterday.
1. "who they are": they're ours, and they are flying around so that they can make sure it stays that way.
2. "what they are": they're the ones which make sure it stays that way (in 1. above).
3. "they come across that fast": which is good, if they were going slower, you'd have to put up with either noise for longer, or a smoking hole.
His house looks like a relatively new-build; can anyone remind me how long Willy town has been operating fast jets? I'd suggest longer than this... man's house has been there.
Those jets mean, old mate, that you still have the freedom to live anywhere you can afford. If you don't like them, you might like to take full advantage of that fact.
