拿大有干货,有高人,找到泰坦尼克的信号了。

好吧,你说的对,但水下也可以烧柴油,老潜艇都这样的。

What we're covering​

  • Banging sounds heard: Sonar picked up banging sounds Tuesday during the search for the Titan submersible that went missing while touring the Titanic’s wreckage, indicating "continued hope of survivors," according to an internal US government memo.
  • Dwindling air supply: Less than a day of oxygen may be left on the vessel, based on Coast Guard officials’ latest estimate.
  • Who's on board: The sub is carrying five people — a British adventurer, a French diver, a Pakistani father and son and the founder of the company that operates the tour, according to social media posts, a family statement.

A submersible carrying five people to see the wreckage of the Titanic at the bottom of the North Atlantic Ocean is still missing despite a massive search operation – but banging sounds were reportedly heard in the area, according to a US governmental memo.

If you're just catching up, here's a recap of the developments so far:

About the excursion: The eight-day journey conducted by OceanGate Expeditions, priced at $250,000 a person, is based out of Newfoundland, with participants first traveling 400 nautical miles to the wreck site, which is about 900 miles (1,450 kilometers) off the coast of Cape Cod, Massachusetts. On this particular mission, the submersible, known as Titan, was carrying a pilot and four passengers.

How the sub went missing: The vessel began its two-hour descent to the wreck on Sunday morning. It lost contact with the Polar Prince, the support ship that transported the vessel to the site, 1 hour and 45 minutes into its descent, officials said. Search operations began later that day. It’s still not clear what happened to the submersible, why it lost contact, and how close to the Titanic it was when it went missing.
A race against time: Less than a day of breathable air may be left on the vessel, based on agency officials’ latest estimate. Some parts of Titan are decidedly low-tech. Unlike a submarine, a submersible needs a mother ship to launch it, has fewer power reserves and can’t stay underwater as long. The ship communicates with the vessel by text messages, and it’s required to communicate every 15 minutes, according to OceanGate Expeditions’ archived website. “All those things we’re used to now – GPS, Wi-Fi, radio links – do not work under the ocean,” according to former Navy submarine officer Capt. J. Van Gurley.

Developments in the search efforts: As the craft’s oxygen dwindles, banging sounds have been picked up from the Atlantic Ocean, signaling “continued hope of survivors,” according to a US government memo. The banging first came every 30 minutes and was heard again four hours later, the internal government memo obtained by CNN states. It was unclear when exactly the banging was heard Tuesday or how long it lasted, based on the memo. Rolling Stone was first to report news of the noise.

The tools being used in the search: The underwater sounds were detected Tuesday by sonar devices deployed by a Canadian P-3 aircraft to find the 21-foot vessel that lost contact Sunday. The US is moving in military and commercial assets as aircraft from the Canadian Armed Forces, the US Coast Guard and the New York Air National Guard continue to look above and below water, and France’s president has dispatched a research ship with an underwater robot to join the search Wednesday.

There were safety concerns: OceanGate touted Titan's safety features, despite conflicting information over its development. CNN has learned of at least two former OceanGate employees who expressed safety concerns about the vessel’s hull years ago, including the thickness of the material used and testing procedures. The 23,000-pound craft is made of highly engineered carbon fiber and titanium. In fact, technology used in the missing Titan sub is so new that it hasn't been reviewed.
这帮人估计平时都坐自己的私人飞机,没有在海关被关过小黑屋,所以凑了几个一起体验

是我孤陋寡闻了,我还以为那套空气系统是支撑柴油机在水下工作呢
 
找不到了,氧气的窗口期快过了,基本上这几位药丸
 
找到了也救不上来。几千米下,那工程不亚于登月
 
水下烧不了柴油,没有足够的空气
弄个浮标, 挂点通气管不就行了。 反正是旅游潜艇, 又不会担心被驱逐舰发现后投深水炸弹。
 
很好奇出动军队的救援,打捞费谁出?
