just checked my emails and I count 10 updates so far this year.
Not just new sites but new features too.
Other apps/websites may list landing sites but
AFAIK Helipaddy is the only one where all the sites listed have been moderated and contain specific instruction and/or cautions.
Add to that the direct links to the site operator, Google Earth views of the landing sites and user comments on the site, quality of the lunch etc.
The £30 fee for the full functionality may only apply for your first subscription, just add another six sites to Helipaddy and you get the next year FOC.
Highly recommended.
