So they had a fluorine facility, and they had a chief technician called Jim Smith who was an absolute marvel. Now I can illustrate that by a very simple story. He met me when we came to the lab and he said, ‘Well sir, welcome to Newcastle. Is there any way I could help?’ And I said, ‘Well, Jim, I’ve heard that you’re an excellent chief technician. I thought of doing some work on iodine pentafluoride and I know that there’s a fluorine cell around here. Do you think some time, you know, along with your other things, we could get some iodine pentafluoride?’ And he said, ‘Yes, sir, I’ll work on it’. That was day one. Nine o’clock on the morning of day two, I came in, Jim knocked on the door – he was already in – came in with a 500 ml flask of this heavy liquid – a beautiful, colourless liquid – and he said, ‘Here you are sir’. And I said, ‘What’s that?’ He said, ‘That’s the iodine pentafluoride you wanted’. And I said, ‘But you can’t buy it. Did you have some in stock?’ He said, ‘No I made it last night for you, you said you wanted it’. And he was brilliant. And when we expanded and got other technicians, he was very helpful in leading them in the fields that we would need help in.
