About a dozen Corona del Mar residents attended Monday's monthly meeting of the Newport Beach Aviation Committee and expressed concern over increased noise.
Corona del Mar Residents Assn. President Karen Tringali said she has received 13 pages of e-mails from concerned residents.
"Many of us have observed planes that appear to be on a more diagonal path," she told the committee. "Last Thursday, one appeared to fly over the clock tower at Marguerite and Coast Highway."
Commercial planes leaving John Wayne Airport in March began using the so-called STREL flight path, which takes planes over the Back Bay to a turnaround point over the ocean. City officials and airport consultants have tracked flight data from the airport and conducted observations, and they say that the flights appear to be taking the correct path. Optical illusions, they said, might make planes seem to be closer to Corona del Mar than they actually are.
