Narrowly Avoiding Mad Cows
I shouldn’t have hopped the fence.
It was shut with a big padlock and surrounded by barbed wire so I can’t exactly claim that I hadn’t noticed it.
But I’d walked such a long way – 5 miles! – just to take some photographs for my blog, it seemed such a shame to give up at the last hurdle. There was no one else there so it wasn’t like I was getting in anyone’s way. And it wasn’t like there was anyone to tell me off – just me and some cows off in the distance.
I didn’t know that they were guard cattle.
But let me start at the beginning…
Brookmans Park is a small village in Hertfordshire, population 3,475. There isn’t much exciting to say about the place: the locals are friendly, the Indian restaurant is divine, the village green is pleasant in nice weather.
However, pilots who fly around southeast England will recognise the name as home to the Brookmans Park VOR (BPK) which is used by aircraft flying in and out of the London area.
When I found out that I was going to be
trapped visiting family staying locally for a few days, I immediately thought of BPK and wondered if I could actually visit a VOR and find out what they look like.
A VOR (VHF Omni-directional Radio) beacon is a navigational aid which broadcasts on a specific radio frequency in such a way that a pilot can get a bearing from the VOR to her aircraft.
If you want to know the detail, the Wikipedia article on VORs is probably the best single reference:VHF omnidirectional range

It turned out that the Brookman’s Park VOR is not actually located in the village but a few miles east near Epping Green. The weather was glorious and I
needed an excuse to get out of the house thought a walk would do me good, so I made my way there, walking along the country roads and enjoying the mild weather.
I used a hand-held GPS and reached the location after about 2 hours gentle strolling.
That’s when I discovered that the VOR was in a field, surrounded by a fence with two padlocked gates.
It seemed so sad. I could see the field and the VOR and a herd of cattle grazing in the distance. I considered my situation for a few moments and then convinced myself that the fence was merely to keep the cattle in, surely not to keep me out. Besides, I wasn’t going to do any harm. I just wanted a closer look at the VOR.
So I clambered over the fence with my camera in hand.
The ground was firm beneath my feet and the sun warmed my shoulders. A light breeze carried the scent of freshly-cut grass to me. The bird song was only interrupted by the roar of the engines overhead. If I had any chance of forgetting my purpose in coming to this lovely location, the air traffic would make sure I was reminded.
I was taught to avoid routing directly overhead popular VORs and VRPs when flying visually. The issue is that flying directly over the VOR effectively concentrates the traffic into a single place. This was the first time I had a visual.
There was never any question of danger, the separation was more than enough but it did feel a bit like Grand Central Station above my head as various low planes from all directions flew straight towards the VOR.
I admit it: I regularly plug a route into the GPS, jumping from VOR to VOR in a dot-to-dot pattern to ensure I don’t get lost. Max Trescott recently wrote about flight safety and indentifying local hotspots and standing at the VOR, I could see exactly what he meant.
This was one.
Despite the traffic overhead, it was a pastoral scene, the golden colours of September all around me, the cattle lowing and a blackbird singing in the distance. I walked closer to the VOR.
It was much bigger than I expected. I stepped around the cow pats and peered up at the phased array antenna. BPK looked both old-fashioned and futuristic, like something I might see in a 1950s sci-fi film.
The two clumps of cattle I’d seen off in the distance had joined forces and come to deal with the intruder.
Of course, I didn’t realise this immediately. I simply thought that they happened to be wandering my way. I took a few more photographs, thinking the juxaposition of the cattle and the VOR would make for an interesting contrast.
So I still did not realise that there was an issue. I thought the cows were interesting and I was pleased for the great opportunity for some nature shots. I looked for a clean bit of grass and knelt down, taking a few more photographs before I realised …
I smiled nervously and gave the cows a little wave. This had no effect at all. I decided that perhaps I had outstayed my welcome. I assured them that I was on my way and that I hoped they had a pleasant afternoon.
I turned my back. Mistake. Never turn your back on a herd of guard cows.
I heard the trotting of running cattle behind me.
I spun around and they screeched to a halt, a few yards behind me, chewing in a melancholy way, pretending that they weren’t after me.
I began walking backwards, keeping an eye on what I now knew were killer attack cattle, ready to defend the VOR against all intruders.
They stumbled forward, slowly closing the gap between us. When I felt the cool touch of shade of the trees, I knew I was close to the gate. I turned around and made a run for it.
The cows clustered at the fence and stared at me. They didn’t make a sound but the message was clear:
I assured the guard cattle that I had every intention of respecting fences in the future. Then I edged my way backwards until I was safe on the main road and I made my way back to civilisation.
And people tell me general aviation is dangerous!
