Due to the developer's failing health, licenses for usage of the IYP application are no longer available for sale.

Negotiations to make the IYP code available to the general public under an open-source model are currently underway. News of these negotiations will be made available as, when and if they materialize.

The developer wishes to sincerely thank the hundreds of IYP users whose suggestions, feedback and assistance have led to the success of the IYP evolution.

There are three individuals whose enormous contributions merit specific recognition and heartfelt thanks. Lars Hammer of Denmark (Pilot# 10083) who has supported the IYP Support Forums over the past decade; Helen Cooper who vetted and maintained the IYP documentation since inception; Mike Sabine (Pilot# 11339) who created, tested and documented the majority of the countless IYP Virtual Air routes.
