NTSB investigators have been on the scene of a deadly small plane crash in a Merritt Island neighborhood all day today -- and this afternoon pieces of the wreckage were removed for examination.

Two local men were killed when the plane went down around 8:30 Monday night.

After removing part of the fence which enclosed this home's backyard, a crew begins taking out pieces of the single engine 2006, Liberty XL-2 plane.

The most recognizable -- the fuselage. Then the tail section. And one of the seats. All put on the back of a truck to be hauled away as part of the investigation.

Killed in the crash was Kenneth Marks, 64, and John Kish, 47, both of Merritt Island.

BCSO said Marks was interested in buying the plane from Kish.

Witnesses said the plane was only 200 to 400 feet off the ground when it spun down towards the ground just a mile or so from the Merritt Island Airport.

Kurt Smith just got back in his house after walking his dogs.

"A boom, and the house shook. Not in a million years would I have thought a small plane has crashed in my yard," said Smith.

The plane landed just feet away from his home. Smith went to help but there was nothing he could do.

Meantime investigators will pour over the wreckage looking into whether a medical problem, or even a mechanical issue contributed to the crash.

They say the plane was equipped with a digital device which could provide them with lots of data. But we don't know yet who was at the controls.

"First we will look at who was where, and then we will look into their experience," said NTSB investigator Tim Monville, who was on the scene all day.

There was no flight plan filed, but it's not required.

The homeowners spent the night at a hotel but are now back home.

About 90 minutes after the crash, a student pilot and instructor were killed in a crash at Daytona Beach International Airport.
