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

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

Harding, 58, is among the five adventurers onboard the submersible that lost contact with its mothership as it reached the site of the Titanic wreckage early Sunday morning. 

Brian Szasz confirmed in a Facebook post on Monday he was the stepson of Harding, before sharing a snap from the band’s San Diego show, insisting his family would ‘want him to be there.’

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

‘How could you go to a concert when that’s happening? Unless that have a really bad relationship,’ Jackie O questioned.

Kyle agreed, adding:’It is a bad look if your stepdad 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 was watching the Blink-182 concert

He captioned it: ”It might be distasteful being here but my family would want me to be at the Blink-182 show as it’s my favourite band and music helps me in difficult times!’

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

A ten-hour countdown has now begun, with the vital oxygen supply expected to run out at 7.08am US eastern time (11:08am GMT, 12.08pm UK, 9.08pm Sydney), a US Coastguard spokeswoman has said.

Hopes of finding Titan are now fading, hours after those leading the rescue said they will ‘hold on hope until the very end’, but admitted that they would at some point need to ‘make a tough decision’.

Rescuers are refusing to give up hope, US Coastguard Captain Jamie Frederick insisted on Wednesday, even as people around the world count down the hours until oxygen is expected to run out on the vessel.

‘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 Titan submersible, which has been missing since Sunday morning with air slowly running out 

OceanGate Expeditions – the company which runs the tours and is responsible for the sub – did not notify the Coast Guard until 5.40pm, DailyMail.com exclusively revealed earlier on Tuesday. 

A total of five people are on board.  The others are OceanGate CEO Stockton Rush, who’s leading the mission, and the world’s pre-eminent Titanic wreck expert PH Nargeolet.

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