A B-25 went down in the Monongahela River near Pittsburgh in 1956. It was never recovered. And the water is less than 20 feet deep!

In 1956 it would have cost more to retrieve the B-25 than it was worth. By 1956 it was just another old WWII surplus airplane.

yes - but how many feet of mud/silt were under it.......

Cessna 172 missed Little Rock's Adam's Field on approach in 2008?. No bodies or wreckage was ever found as it plunged into the Arkansas River. People fishing on the banks and a barge went to the splashdown and marked the area......Fire and rescue showed up in 7 minutes and it was still never found. Not a trace.

I have ALOT more respect and fear for that river now.

Ok. Listen to me, and listen to me good.

There is methane under the earth’s crust. Methane is lighter than air. Sometimes a large bubble of methane flatulates out of a crack in the crust, sometimes under water. (You may have seen something like this while taking a bath...) If a plane or ship happen to be over the bubble, they immediately sink because there’s nothing to hold them up. Starting to get the picture? So the plane or ship are suddenly underwater and there’s no sign of where they went. It’s not like when they crash on land. So that’s my take on this and the bermuda triangle too.
