I have an invitation for the wedding of a friend in the Middle East. The couple wanted me there so they are going to send me a round trip plane ticket. However, my concern is not the expense but my safety against the covid virus. Riding in a plane would expose me. The plane is an enclosed site with air conditioning inside that will stir the air and will make the airborne virus more dynamic. That got me thinking. Even if I have the vaccine but there is no assurance of my safety.
