oHelipaddy, the world's largest moderated database of helicopter landing sites and points of interest, now contains around 5000 moderated sites. Their effort is now on making it easier for pilots to find the best places to go - the ones that require very short notice, or are in particularly nice spots. To help with the UK, they have partnered with The Good Hotel Guide who have been in operation for many years.
