Starfighters Aerospace operate the single and 2 seater F-104, you can even have a go if you want "Pricing starts at $30,000 US for a single flight training program. Add a second flight for $23,000 more."
The collins foundation have an F-4C/D, T-33, TA-4J, F-100D. It actually took them an act of congress to get the an an amendment to the Defense Authorization Bill to make this happen, so they must have pwerful friends!
Cant see the CAA ever allowing Afterburner jets in the UK.
