THE top experts who probed the fall of the Twin Towers after the 9/11 terror attack have been drafted in to investigate the Miami apartment block collapse.
US Congresswoman Debbie Wasserman Schultz revealed specialists from the National Institute of Standards and Technology (NIST) gathering key evidence.

However, Florida governor Ron DeSantis made it clear that the team's in-depth study into what actually caused the tragedy will be a long-term project.
"It is something that is going to be very thorough and is something that is not going to happen in a day or two. This is going to take a long time," he warned.
He added the search for survivors had been and the outbreak of fires, as it was revealed the death toll has risen to 11.
"[Rescuers] have been going at it for over 100 hours straight - when there's danger, they run towards it," he said.
"They obviously shepherded a lot of people to safety initially. And they have been every minute of every day since the building collapsed, trying to identify survivors."
"They're putting themselves at risk in order to do that, not only because you could have additional collapse.
"You've had deep seated fires that they had to fight. It's been an incredibly hazardous environment and they've been on the scene non-stop from the very beginning."

A resident of sister tower, Champlain Towers East, shared photos of a massive crack that appeared after on Thursday morning.

"They're learning that some of their loved ones will only come out as body parts."
The search efforts entered a fifth day on Monday, as hope waned that any more survivors would be found amid the massive piles of rubble.
Miami-Dade has created a larger family assistance center for people whose loved ones have been missing since the condo collapsed in the early hours of Thursday morning.
