The canopy on the original aircraft in Finland has a different structure to the one shown !

It has finer glazing bars and fillets at base and no upper cross bar.

Without seeing the data plate  I am assuming this is Viscount Pilot seat.

Similar one for sale here that I told them was not a valiant seat.

Anyone with an empty viscount cockpit ?

Not Ebay but auction house- a DH Heron cabin door.

Avialogs has the maintenance manuals for Hercules 630 and 760 if they were of any use.

Thank you AmarokUK the map shows them passing directly above us around 1330.  

Hopefully payback for the number of times they have sneaked in a rooftop height above us to play at Spadeadam.

Seems only a short while ago that the three Tornados passed this way on their final flight.
