Dont be daft , in 50 hrs time they will be wanting to come up and watch dad fly and enjoy the experience as much as you will, this will lead unfortunately to you having to start paying for flying lessons in 10 yrs time when they deciede they wish to become pilots .It isnt just you who is going to enjoy this experience its one thatyou will be bringing to your entire family . It is as safe as a safe thing thats safe , go forth enjoy .
good luck
