Can I throw this into the mix gents?
I use Aerodata as my main spotting software repository.
With their database, it is not possible to download the data in its entirity or in part, for other people/organisations to benefit from, but it is possible to add information to records and add unused empty fields for individual users unique benefit.
To my best understanding, this isn't a million miles away from the options with v5?
It's not unusual therefore for database providers to guard their work?
