Oh, the noise those aircraft make! I had occasion to email the MoD last year.
"Sir
I was standing on Manningtree railway station at about 0945 when I plainly heard in the North West an AH64 manouvering hard. I searched the sky but was unable to locate it. Only after a minute or so did it suddenly pop up above the treeline, still making steep turns at high speed. It passed over the railway line to the west below 100ft and was quickly lost to view, but not to the ear.
I feel I must take this opportunity to say how much I
appreciate this kind of flying. It's better than an airshow! Please pass my good wishes to the pilot and I look forward to more such demonstrations."
The MoD replied sounding fairly pleased.
