He started at the Air Force's historical records agency down in Alabama, but the search ballooned wildly from there, into the National Archives, and then into interviews with surviving airmen from the unit. And then it continued onto these missions that he began making at least once a year to Palau, with a backpack full of gear, which over time became increasingly complex technology that he would use to try to find the airplane, including magnetometers and infrared film that he believed he might be able to use to see through the water in the channels of the islands. So he would strap himself into the open doorway of a Cessna and have a pilot fly him over these channels and he'd be hanging out, you know, almost parallel to the surface of the water.
But the problem was all of the accounts of what happened to this airplane were different. The stories that family members heard were different from the official story that they heard, which (was) also different from the stories that Palauan tribal elders who had observed the crash heard, and so none of it added up, and it was very hard to even have a sense of where he should be looking.
On the moment when, after a decade of searching, Scannon and his team found what they believed to be the rest of the plane
It was a moment of great joy and also great sorrow ... I've seen footage of the day that that plane was found, and you can see both those emotions so clearly on the faces. There's this sort of ashen-faced horror at having found the wreckage of at least part of this aircraft. And yet there was also this sense that after having spent the first decade of this process searching and searching, wondering, that they had finally come to a point of some clarity about at least where most of the plane and many of the men wound up.
On why the son of one of the airmen traveled to Palau to dive down and see the plane himself
He told me that when he went down to the plane he still wasn't sure whether his father was on it. Like so many families, he had grown up wondering if his father had perhaps found some way to get off the plane and survive. So he got to the dive site and he made his dive down and he saw the waist-gun door — this huge yawning opening where the 50-caliber machine gun sticks out. And he reached out and he touched the plane, and he held on, and he had a conversation with his father for the first time ever, feeling that perhaps his father was there — although he still had no way to know for sure.
