Aviation experts testified before the City Council Tuesday over ways to make the city's air space safer following the deadly mid-air collision over the Hudson River earlier this month.

At issue is the unregulated area around the river below 1,100 feet. Among the ideas that were floated was regulation of the space, including requiring pilots to submit plans before their flights and requiring high-tech navigation systems.

Both sides of the debate voiced their opinions.

"If we cannot come up with the regulations that work and are implementable, ones to which the FAA can be held accountable, then we would have no choice but to go for an all out ban," said City Council Speaker Christine Quinn. " I think everyone's hope is to try to find something that would bring regulation that will deal with quality of life issues and deal with safety. That is certainly not the case today. I hope we can get there and I hope we can get there quickly."

"If you're talking about banning of helicopter flights around New York City or restricting it, that's gonna hurt our industry but that's a quality of life issue," said David Damelio of the New York Aviation Management Association. "I don't think the FAA comes out and says it's a safety issue and helicopters can't exist anymore. Then they have to do what they have to do. But I don't restrictions set aside from elimination of flights think hurts the industry. We welcome that."

The FAA did no attend or comment on the hearing, saying the investigation of the crash is ongoing.

The agency is looking into new regulations over the Hudson River and is expected to release a report in the next few weeks.
