Canadian aircraft detected underwater noises in the search area for the missing Titan submersible, the US Coast Guard said early on Wednesday, amid US media reports that regular banging sounds had been picked up.

The discovery on Tuesday led search teams to relocate their underwater robotic search operations “in an attempt to explore the origin of the noises”, the Coast Guard said in a series of tweets. The searches by remotely operated vehicles (ROVs) came up empty-handed but would continue, the Coast Guard said.

The Coast Guard did not state the nature or extent of the sounds, or how they were picked up.

Investigators from around the world have flown in to try to explain the sudden, middle-of-the-night collapse of a nice enough, but largely unremarkable luxury condo building, one that stood for several decades before collapsing but wasn’t nearly as old as some nearby buildings that still stand. It’s nearly unprecedented mystery that experts are struggling to explain.

“It’s really rare to have this kind of failure that a building is doing all well and all of the sudden it just collapses,” said Mohammad Ehsani, engineer and concrete-shoring expert. “It’s not something that should happen or does happen.”

It seems hyperbolic to say “40-year-old buildings don’t just collapse” but it’s not.
