Titanic 2.0
A Canadian P-3 maritime patrol aircraft detected "underwater noises" in the area where search and rescue crews are looking for the missing Titan submersible that went missing while diving towards the Titanic's wreckage with five people on board. "The sounds from underneath the water were heard by sonar devices deployed to find the lost 21-foot submersible. The banging sounds came every 30 minutes when first detected Tuesday and were heard again four hours later," CNN said, quoting the memo.
