I'm a bit old for Corporate Comms and lacking in the Facebook/Twitter skills probably required nowadays.
I wouldn't claim to understand NATS financing, I got confused when the Airline Group bought half of NATS for several hundred million and somehow NATS paid the Treasury. However I think you need to look at total borrowing before and after that deal and how much of that profit over the years was reinvested.
I am however in awe of the gentleman who somehow sold bonds for a company with no real income in the middle of a pandemic. I'm not surprised they gave him a pay rise.
