One of the reasons for the new airport at St Helena is that the tub that shuttles to & fro is near the end of it's life - the cost of replacing isn't a lot but the cost of running it for another 40 years is apparently horrendous
Correct, leading to the amusing Treasury suggestion to the FCO / DFID that they should consider buying a
long-range Beriev-200.... not that the FCO got the joke IIRC. (Well, it would've cheaper than blasting the runway out, and where else can you take a flying boat on holiday?!)
