(CNSNews.com) - Sen. Gary Peters (D-Mich.), chairman of Homeland Security Committee, attended a briefing on Tuesday about the three objects the U.S. Air Force shot down this past Friday, Saturday and Sunday, but Peters says he came away dissatisfied:

"I was certainly frustrated not to get more information as to exactly what did the pilots see, what was their description, videos taken, why haven't we -- why don't we have an opportunity to see some of those to judge for ourselves? And again, a better sense of what exactly we're dealing with here?" Peters asked during an interview on CNN.

"That information, I think, is very important, and people certainly have the right to know."

Peters said the briefers, including members of the intelligence community, did give senators some information on "how systems work."

"And that's very classified. People should not know how surveillance systems work and sensors. And that information was certainly provided, I thought -- I found that very helpful to understand what tools are being used to evaluate objects. That's fairly clearly classified and needs to be protected. And certainly, that was provided."

But Peters said he didn't hear anything about the origin of the objects: "And certainly, it didn't appear like there were markings of any kind, at least that were shared with us in the briefing as to where that may have come from, if it was commercial, whether there were -- there are any markings related to that.

"None of that was very clear. But that's why it's important for us to have a chance to take a look at any images were taken of these objects. And that was not provided to us today."

Host Victor Blackwell asked Peters, "Is it time for the president to speak to the American people about this?"

Peters said there's been a lot of talk about the unidentified objects and people are concerned: "I think after we get more information, if there's more information to glean, the president should certainly let people know why we shot down three objects, it is a -- it is certainly a concern for folks. And transparency is always a good thing," he said.

Peters and others at the briefing came away with the conclusion that the objects, whatever they were, were "benign."

"It certainly is the leading theory right now. And you know, one thing though was very clear that I -- want us to be public is that they did not believe that these objects had any weapons, and were any kind of threat to anybody in the United States.

“There was no, as they say, kinetic, there was not going to be any kind of explosions or bombs on it, so -- and that's what at least the pilots were assessing who were checking out these objects.

"But the main reason for their concern was their altitude. They're in an altitude that could present a real hazard to commercial aircraft that are operating in that space. And there's no question if a -- if a jet would hit that object and could have serious consequences in that navigation. So, that was the decision for a while to bring them down.

"But clearly, we're not going to know exactly -- it was clear, we're not going to know exactly what they were until or if we are able to recover any of the debris. And that's looking very difficult."
