Thank you for your comments, and for reaching out to me.
My beautiful husband returned home to heaven this morning, and I feel privileged that he let me be by his side when the time came. I still can't believe he won't be coming home again.
He loved flying and was an excellent pilot - about half an hour after he passed, I heard a small aeroplane circling overhead. One of the nurses also saw it - a Tiger Moth. I knew he sent it to us to let us know he was OK.
