Depending where I am in the valley, I have on times been able to look the pilot eye to eye - once I found myself looking down into the cockpit!They fly that low in the valley where I am. It can be a bit disconcerting as they suddenly appear and are gone, often just above the property. Glad I bought a bungalow.
Yep....we get something similar here in twos and sickeningly loud from nowhere.Had one fly overhead when I was working in Sennybridge, you could practically touch it. Worse still in and around that area were the Tornadoes. Wouldn't hear them coming, just a sudden, sickening roar above and then gone. I had this at Llandefalle, so loud it froze me but all the livestock carried on grazing and didn't bat an eye.
Having dinner up on the common, I watched them flying along the valley below me!!
