It seems that Caverton is still around as their 109 was seen yesterday over Lagos.
I also hear from a friend in Portugal that a Dauphin has been seen flying around Estoril in the last few days. It's a dark blue colour with the Heliportugal logo on the top and the Caverton logo on the tail, but still on a Portuguese registration. Perhaps the rumour which has been around for a while of them bringing another helicopter to Nigeria, is about to prove true. Certainly they're now advertising a shuttle service in Port Harcourt on their website. No sign of 'Uncle Bob' to confirm or deny the rumours though.
