I suppose the seats must be inert on it
If you look closely at the footage of the JP front end, the bang seat triangle cleary has Inert written on it.
A very good programme in my view as it had at least one item in it that I wasn't aware of in the US trying to stop the export of the Comet (and I could have written most of the script for it off the top of my head). However having researched the Files at kew about the export of Bloodhound to the Swedes and Swiss, I was aware that the US tried to stop the export of the Mk 2 to the Swiss on technical transfer grounds. The guys at the FCO were quite clear in the documents that it was purely sour grapes on the part the Septics seeing that they had already cleared the Swedish deal.
