The missing tourist submersible with five people onboard including British billionaire Hamish Harding, has been slammed by Good Morning Britain viewers who have insisted it was 'foolish' to go on such a mission.
Meanwhile others have criticised host Richard Madeley for his 'bad taste' approach to discussing the sensitive topic.
A massive search and rescue operation is currently underway in the mid Atlantic after the tourist submarine went missing during a dive to the sunken Titanic shipwreck on Sunday.
Contact with the small submarine was lost about an hour and 45 minutes into its dive, and the passengers will only have Oxygen until Thursday at 11am, after which it will run out.
The trip, which is thought to cost £195,000 per head, launched at 4am on Sunday, but communications disappeared less than two hours into the descent to the Titanic wreck site - which sits about 3,800m (12,500ft) below sea level at the bottom of the ocean around 370 miles off the coast of Newfoundland but in US waters.
The missing submarine was designed with a 96 hour 'emergency capability', Rear Admiral John Mauger, who is leading the rescue mission, announced at a press conference this evening - meaning there should be enough oxygen in the vessel until around midday on Thursday.
There are fears that the submersible, named Titan, could be stuck in the wreckage of the Titanic that it was diving to explore.
However, some Good Morning Britain viewers have said they have 'zero sympathy' for the passengers onboard.
Discussing the concerning situation on Tuesday morning's instalment of the ITV programme, hosts Susanna Reid and Richard Madeley shared their hopes that the submarine is found and the passengers are rescued safely.
Richard did however then read out a number of tweets from people who have slammed the entire expedition - a move which many viewers at home found insensitive.
"They should have just left the Titanic alone. Thousands of people died on that ship. Let is rest. These people have far too much money for their own good," one viewer fumed.
"This is awful, but now more people have to risk their lives to try and save these people. All seems a bit idiotic to me. Hope they are found safe and sound though," another echoed.
Another GMB tweeted: "I think it's time that people should just leave the Titanic alone and have some respect for all the lives of the people who were lost."
"Don't agree with Richard and Susanna at all. I have zero sympathy for these people," another viewer complained.
Elsewhere, others slammed Richard for his decision to read out the negative tweets in the first place.
"Was there any need for Richard to read out those negative tweets? Not really the time or the place," one complained.
"Not Richard actually reading out all those horrible tweets on air. Switching off," another fumed.
The expedition was OceanGate's third annual voyage to chronicle the deterioration of the iconic ocean liner that struck an iceberg and sank in 1912, killing all but about 700 of the roughly 2,200 passengers and crew.
