In this category we intend to deal with our visits to different airfields in the course of years staying outside the gates and fences , NOT KNOWING BEFOREHAND IF THERE WOULD BE ANY FLYING ACTIVITIES . Also when we did know that there was an exercise or deployment going on , it was still not certain if we would be successful. Sometimes we had to leave without having seen any or very few airplanes taking-off or arriving , which is very disappointing but that is the chance we took.
