A wrong word can destroy friendships, or as in our case, force a change of plans for our IOP5. When calling in at 5 this morning to deactivate the Danger Zone “Hailuoto West”, we are flying in, I used the phrase “….we are done for the day…” instead of ” …. we are done for the night….”. Therefore the activation was terminated for all of the day and it is apparently not possible to re-activate it again. That means that all our operations for the short IOP until midnight will be limited to a maximum altitude of 150 m above ground. Lesson learned! Be careful what you say.
