I listened to an interview with the owner of the company on the radio this morning. He's a commercial real estate investor who sold everything near the start of the pandemic (smart). He then decided to form an ocean exploration company to search for things like lost planes and ships and such. He chose this as his very first search because he was curious, but also because he wanted to generate publicity for his company. They set up a 90-day search mission and were filming it for a documentary. And they found the object on literally the very last day of the search. They say it could be the plane, but that it could also just be a group of rocks in the shape of a plane. He's already gotten one [person? company?] to hire him to look for another lost item underwater and had other inquiries.

Honestly? I don't think it's the plane, just a guy drumming up publicity for his new business, especially since it's in a field that he's not established in. They're going to go back and either not be able to find that image again, or it'll turn out to be a bunch of rocks. Possibly even a bunch of rocks they spotted earlier and came back to in the last day with the idea of "eh, close enough" for publicity purposes. As for the image? Remember this?

They've found a definite indication of a need for investor and grant money
