staplefordheli, I suggest you talk to your son and explain aeros are not dangerous, and when he grows up he could get his pilots licence and join in the fun. As for the missus buy her a flight in a Pitts (there is one at Sibson) for her birthday, and make sure a few rolls and loops are included. Then you can go away on business safe in the knowledge those pesky Pitts will not scare them again, and they will actually enjoy watching the display. Job Done.
