Monday, February 15, 2009 — For the better part of an hour, helicopters have been circling over the Hilton Gardens Hotel in Portsmouth, covering a carbon monoxide incident. One woman was reported to have been found unresponsive, and eleven people have been treated for symptoms of carbon monoxide exposure. Everyone in the downtown area has been subjected to more than an hour of gratuitous noise.
Yup sometimes vehicles emit carbon monoxide it is a harm full gas it can lead to many disorder. It is like ship captain suffers from motion sickness. Hilton Gardens should stop circling helicopter over them or they should monitor the carbon monoxide emission
