Kyle Sandilands and Jackie O Henderson slam stepson of billionaire aboard the missing Titanic sub

Kyle Sandilands and Jackie O Henderson have scolded British billionaire Hamish Harding’s stepson for attending a Blink-182 concert as his relative is still missing on the Titanic submarine.

Harding, 58, is one of five adventurers aboard the submarine that lost contact with the mothership when it reached the Titanic wreck site early Sunday morning.

Brian Szasz confirmed in a Facebook post Monday that he was Harding’s stepson, before sharing a photo from the band’s show in San Diego, insisting his family “would like to have him there.”

Speaking on KIIS FM’s The Kyle and Jackie O on Thursday, Kyle said attending the concert while his stepfather is missing is “a bad look.”

“How can you go to a concert when that happens? Unless they’re in a really bad relationship,’ Jackie O wondered.

Kyle agreed, adding, “It looks bad when your stepfather is at the bottom of the ocean and probably dead in 10 hours. [and you’re at a concert].’

In his original Facebook post, Brian shared an image outside the San Diego venue where he watched the Blink-182 concert

He captioned it: “It may be unpleasant to be here but my family would like me to be with the Blink-182 show because it’s my favorite band and music helps me through tough times!”

Meanwhile, the search for the missing tourist submarine Titanic continues.

The ten-hour countdown has now begun and vital oxygen supplies are expected to run out at 7:08 a.m. US Eastern Time (11:08 a.m. GMT, 12:08 a.m. UK, 9:08 p.m. Sydney), a US Coast Guard spokeswoman said.

Hopes of finding Titan are now fading, hours after those leading the rescue said they would “keep hope until the end”, but admitted that at some point they would have to “make a difficult decision”.

Rescuers refuse to give up hope, US Coast Guard Captain Jamie Frederick stressed Wednesday, even as people around the world count down the hours until the ship’s oxygen is expected to run out.

“We have to remain optimistic and hopeful when we are in a search and rescue case.

Hamish Harding is one of five passengers aboard the submarine Titan, who has been missing since Sunday morning as the air is slowly running out

OceanGate Expeditions — the company that manages the tours and is responsible for the submarine — did not notify the Coast Guard until 5:40 p.m., DailyMail.com announced exclusively earlier Tuesday.

In total there are five people on board. The others are OceanGate CEO Stockton Rush, who is leading the mission, and the world’s foremost Titanic wreck expert PH Nargeolet.

Also on the submarine are British-Pakistani billionaire Shahzada Dawood, 48, and his 19-year-old son Sulaiman.
