I am very careful who I fly with. I was at the airfield a few years ago and one of my mates asked my missus if she'd like to go for a flip in his Citabria. I took her to one side and even though I'm not one to spoil her fun, I said on no account is she to fly with this guy - his approach was too lassaiz faire and he loved doing aerobatics over the airfield. he was a real nice guy and competent enough but I always had a bad feeling about his attitude. Two weeks later he wiped himself and his Citabria out doing low-level aerobatics.
