watching. It had landing lights on, around 10 miles from the airport
and had white lights flashing on wing tips. I couldn't see any
navigation lights. What might that have been doing?

Planefinder.net does show a single aircraft arrive from the south, swizz
around for a bit (doesn't look like 40 circles on screen, but don't know
what resolution/interval it records at)

Seemed to spend longer over Huddersfield earlier in the afternoon

aircraft is G-POLV, which is a national police plane, so that seems to fit

The centre of the tight circles was gradually drifting. It was too far
away to ID the type of aircraft, which had the setting sun behind it.
I've never seen one before with flashing white lights on the wing tips.

Interesting link.

But I cannot find a plane landing at Doncaster on the 12th (10.10am to
10.20am ish) that must have landed (I could not see the runway) I was
halfway between Tickhill and Bawtry.

Are military plane hidden from that site?

I don't know if military planes have ADS-B transmitters, or some other
system, or maybe they're allowed to turn them on/off as required?

And how big a plane, you often see twin engined prop jobs doing that over
traffic hot spots or some event or other here near London apparently.

At one point in time, one of the London ILR stations used to use such a

Police sometimes circle while using Stingray or similar to intercept
criminal or other suspect mobile phones, but they wouldn't normally do
it very low. I suppose they might have been constrained by the proximity
of an airport. At one time you could sometimes see this activity on
FlightRadar but now I think they have the option to prevent it being
displayed.

Do West Yorkshire have an police aircraft, I know they have an

I saw two military aircraft yesterday (Fri) flying in formation over
Prestwich (3 mi N of Manchester) going roughly North.

SWMBO suggested it might be to do with the D of E funeral.

Not usually viable, too hard to focus on what you are photographing.

That depends upon the type of airport, the type and size of aircraft and
how busy it gets. Most of the holding points for my local airfield are
rarely used because it rarely gets that busy.

and they don't do that in very tight circles.

Flying VFR, you have to keep a lookout for other aircraft. That is much
easier when orbiting (flying in a circle) than when trying to fly a
racetrack. You can orbit purely by using external references. A
racetrack hold needs you to spend a lot of time looking inside the
cockpit at your instruments and at the time. Not a problem when flying
IFR, as ATC radar should keep you safe from other aircraft. A serious
problem when trying to keep a lookout for other aircraft.

It doesn't work that way. The forces are downwards through your seat, so

There was a newspaper (forgot which one) story recently about the
police in Scotland somewhere have bought a few planes and then found
them unsuitable for what they wanted. They were trying to sell them
(cheap) to some UK forces. Maybe this was a trial by prospective
buyers.
