The comment "One of the most recent deployments of an aerostat was seen at the opening ceremony of the nineteenth 2010 Commonwealth Games, held in Delhi, India." is trivia, or at best a promotional reference. Certainly by now it is out of date, because more recent deployments of aerostats have been seen at many major sporting events since this event, every time an advertising blimp such as those operated by Goodyear overflew them.
