The aircraft is still flying and if you either (a) contact via the website above or (b) write to "Friends of the Heron", c/o Jersey Aero Club, Jersey Airport, St. Peter, Jersey, it should get there. The aircraft does have a list of flying engagements and I will try to find out what these are. Some take the aircraft to the UK.
I have flown on the aircraft once and I do see it flying around now and again and it's a great old plane.
Interestingly, although the Heron is usually flown by two retired BA 744 captains, it can be flown by a single pilot (it used to be in RN service), making it the only single pilot four engined plane.
