An interesting website run on behalf of private pilots. Aimed at avoiding airspace infringements, but the "Hot New" section has some good info in PDF format.

There are some interesting radar replay videos on the site too:

Another interesting site run by the Airspace & Safety Initiative group a joint CAA, NATS, AOA, GA and MoD effort to investigate and tackle the major safety risks in UK airspace.

The group is also on Twitter if you use it:

Familiar with that site. I built the original recordings as an adjunct to those I was producing at LTCC for the Training section and Investigation unit, and others. For Flyontrack (and other public access sites) I had to remove the code callsign conversion to de-identify for obvious reasons. I trained up a nice chap from Manchester, who I think is now producing the recordings.
