(CNN) -- A former Microsoft executive and his son were aboard a turboprop airline that crashed Friday morning into two houses in East Haven, Connecticut, a family member told CNN.

There has been "no official confirmation or positive identification" that Bill Henningsgaard and his son were on board, but there is no reason to believe that it was not the two of them, his brother, Blair Henningsgaard, said.

Also feared dead in the crash were two children -- ages 1 and 13 -- in one house, East Haven Mayor Joseph Maturo Jr. said. The other house was unoccupied.

National Transportation Safety Board investigators cannot confirm the number of people killed, saying there are reports of four to six people dead.

Connecticut Gov. Dannel Malloy said there could be as many as five people killed in the crash, including up to three people on the plane.

But Blair Henningsgaard said only his brother and his nephew were believed to be on the plane.

Two bodies were seen inside the home but haven't been recovered because the home is unstable, East Haven Fire Chief Douglas Jackson said at a press conference Friday afternoon.

Fire consumed both houses, preventing firefighters from searching for victims, Jackson said, and the basement in the home holding at least two victims was filled with water.

Maturo said the children were in one house with their mother when the plane struck shortly before 11:30 a.m. The mother escaped, he said.

"It's ... total devastation in the back of the home," Maturo said. What are the answers to this following set of questions: 1. Which Connecticut official said there could be five people killed in a plane crash?

Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Antarctica is considered a desert, with annual precipitation of only 200 mm (8 in) along the coast and far less inland. The temperature in Antarctica has reached 89.2 C (128.6 F), though the average for the third quarter (the coldest part of the year) is 63 C (81 F). There are no permanent human residents, but anywhere from 1,000 to 5,000 people reside throughout the year at the research stations scattered across the continent. Organisms native to Antarctica include many types of algae, bacteria, fungi, plants, protista, and certain animals, such as mites, nematodes, penguins, seals and tardigrades. Vegetation, where it occurs, is tundra.

Geologically, West Antarctica closely resembles the Andes mountain range of South America. The Antarctic Peninsula was formed by uplift and metamorphism of sea bed sediments during the late Paleozoic and the early Mesozoic eras. This sediment uplift was accompanied by igneous intrusions and volcanism. The most common rocks in West Antarctica are andesite and rhyolite volcanics formed during the Jurassic period. There is also evidence of volcanic activity, even after the ice sheet had formed, in Marie Byrd Land and Alexander Island. The only anomalous area of West Antarctica is the Ellsworth Mountains region, where the stratigraphy is more similar to East Antarctica. What are the answers to this following set of questions: 1. Which continent is the coldest?
2. The driest and windiest?
3. Which continent is generally more above sea level than Antarctica?
4. Does Antarctica get lots of snow?
5. Which is wetter, the coast or inland?
6. Are polar bears native to Antarctica?
7. What animals are?
8. Any others?
9. Can you name three others?

Answer: 1. Antarctica
2. Antarctica
3. unknown
4. No
5. The coast
6. No
7. Mites
8. Yes
