As an enthusiastic kid Diamonds in the Sky was fantastic.
Back in the 70s there was little coverage of Aviation other than the clichéd annual coverage of the Biggin Hill display. (RIP Raymond Baxter. Great feller).
The one episode that I found particularly fascinating was the story of the Empire Flying boats that had their heyday and made Foynes temporarily a very important staging point in Ireland.
It must have been extraordinary for locals to suddenly appear a hive of activity at the centre of the world only for it all to ebb away as the boats became moribund, and for it to become a quiet place once more.
They must have dreamt that it all happened.
