Terrifying moment tandem skydivers are critically injured in Florida after their parachute malfunctioned and they hit a tree (7 Pics)

This is the terrifying moment two skydivers are seen barreling toward the ground after their parachutes malfunctioned.

Footage from the incident in Titusville, Florida this morning shows the men spiraling off course before they hit the ground on the 900 block of Tennessee Street.

In a video recorded by nearby witnesses, shocked onlookers are heard saying in disbelief, 'oh my god' and 'they're going down'.

The footage was obtained by ClickOrlando, which reported that Space Coast Skydive owner Greg Nardi said they’re looking into what happened but added it appeared everything was working properly when a master jumper and student took off.

Images show their blue parachutes tangle in a large tree branch that appeared to break off from a tree and thud on the ground with them.

Brevard County Fire Rescue responded to the crash-landing scene, which was in someone's front yard, at approximately 10.28am.

The duo were assessed and declared trauma alerts, Titusville Fire Department said Wednesday.

Orlando Health Air Care 3 and Health First Trauma Center and First Flight Air Medical Transport arrived to airlift them to hospital.

Titusville Fire Rescue praised the 'great team work' from the departments to get both patients out of the harness, packaged and treated while awaiting air transport.

They were in a trauma center in critical condition, on Wednesday evening. 

According to the Titusville Police Department the two victims, were part of a tandem jump from a plane that originated at Dunn Airpark.

Law enforcement said Wednesday evening it is still investigating the incident.

The names of the victims were not released. 

Authorities did not state whether the victims were jumping with a skydiving company but Skydive Space Center operates from Dunn Airpark.

On the company website they state that tandem skydiving is the safest option for a first-time skydiver. After a safety briefing the jumper is taken to a plane, harnessed to their instructor and then they free-fall for a minute from 18,000 feet up - one of the world's highest jumps.

When the instructor opens the parachute the sail down is supposed to last 4-6 minutes.
