Complaints about noise coming from aircraft ferrying visitors and locals to and from one of America's best-known playgrounds for the rich and famous have more than tripled over last year, due in part to a new service that lets people book 40-minute chopper rides from Manhattan for relatively cheap prices. Between the helicopters, corporate jets, seaplanes and other aircraft, residents say life in the vacation paradise has become a nightmare. Bob Malafronte, a retired New York City teacher who lives in Sag Harbor and is a member of a noise abatement committee, said he wants either an outright ban on helicopters or a requirement that they fly 20 miles farther east over Long Island Sound and then turn south over Peconic Bay — keeping them over water for a longer time. While chartering a helicopter ordinarily costs about $3,000 a trip, a new service called Blade that operates out of New York City allows passengers to buy individual seats on choppers for about $500 a trip. Jeff Smith, vice president of operations for Eastern Regional Helicopter Council, a trade group that represents operators of about 110 helicopters in the New York City area, said figures are still being analyzed for the cheaper helicopter flights, but a new market has definitely been tapped.
