A licensed operator lied to me about a film student being licensed and vice versa. Can I still use the footage in a commercial film?

Hi, im sorry if this is against sub rule. But I have a complicated problem and I know next to nothing about drones other than how to fly one. I posted on another sub and got one person commenting saying I should be ok.Pretty much I took in this youth filmaker who won a grant to help them. I got my coworker to help as well because he is the licensed drone operator. Things go well until I had to take a leave of absence following a stroke. Thankfully I recovered and was back to work five months later.The drone operator said that the student had gotten his license to fly for commercial reasons. So we set off and made the film. We went to many abandoned and rural mountain sites, abandoned mines and such, it was quite the adventure. The film is done and was screened privately.My student thanked me and mentioned he was happy I got my pilot license as the drone operator had been unhelpful. Confused, I asked the drone operate, who basically said "I just told you two the other one got his license so I don't have to deal with it".So in short, most of the drone shots, about 5% of the film was unknowingly shot without a license. I have not disclosed this stood my student yet, but that may mean we cannot release the film. It really hurts me to think that way but I don't want us to get fined. Especially when we were tricked by a licensed operator.So my questions are basically, is the footage unusable legally? Is there a way I could pay to be able to use the footage? And lastly, can I report the drone operator because of what he did?Again I am so sorry if this is in violation. I just need some clarity because I don't want to dash this kids dreams by pulling the film and he has to sell it commercially because the grant specifies such. I have talked to some of the other higherups and they are split. It basically ended with them saying that I'm in charge of if we should pull it or not.I'm just worried of potentially being fined or hurting the company but the latter may be unavoidable at this point.Also to clarify, it is too late to shoot new footage. The grant deadline passed just a month after the initial cut of the film was completed. I would happily pay out of pocket to license the footage. My student is so happy with his film, I don't want to ruin things. via /r/drones http://bit.ly/2YRZaIk
