when they crash in the water they certainly can - of cousre there is the mythical flying sub from "voyage to the bottom of the sea" - it is possible to make a winged craft or lifting body that would "fly" underwater but its ineffecient since underwater craft dont need to fly as it is more effecient to make them bouyant - wings are used in subs in the form of control surfaces
if one were to design a "flying sub" then the design from "voyage" is probably the most practical using a lifting body design - wings would be too fragile due to the heavy weight of water creating huge forces on the wings
Bathtube AerodynamicsYes. By this I mean that a plane can "fly" under water just as it does in the Air. In the 1960's, a professor at Mississippi State University, Professor August Raspett, helped design STOL vehicles and was involved in other aerodynamic research. Today the aerodynamics lab located at the local airport is named after him.Professor Raspett and his young son wrote a technical paper called "Bathtube Aerodynamics". It was actually his son's idea and his father assisted. The son wanted to take a model airplane and try to fly it in the water. The typical model he used was the scale plastic models----or as you would call them---plastic kits. It actually works. Why? The equations for fluid flow is the same for AIR as it is for WATER. Only the Reynolds Number changes.
First you have to trim the model for proper CG. Plastic kits are built to scale but the model is not have correct Center of Gravity. Some models had to be altered. Some holes have to be plugged. For example: a model of a jet may have a large opening for the engine inlet which may require plugging to prevent disruption of the flow. The wings and tails have to be perfectlly aligned so they will produce lift. If it had a propellor, then it had to be removed to reduce drag. The model can then be launched under water and it will glide just like it was in AIR. Since the Reynolds Number for water is higher, the model will "fly" slower in water---but it will still fly.
He also tested different models using rubber-band powered propellors. And they could glue some chemical(forgot what you call it) to the model and as it went through the water it would leave a blue contrail left from the chemical exposure to water. This could be used to study the votex and airflow.
Really cool. Possibly a great idea for a high school science project.

MORE ABOUT "BATHTUB" AERODYNAMICS
some fish actually fly like airplanes - fish like sharks have no swim bladder to keep them bouyant so have to stay in motion, or fly, to keep from sinking - many like the shark have bodies that are lifting bodies and their fins can act like wings to give extra lift - think of the manta ray as the ultimate marine aircraft.
Also Penguins and even ducks can "fly" underwater. Of course they have the advantage of flapping wings instead of fixed wings.
What else can I help you with?
Are there special helicopters for water?
yes, there are but it depends what you mean. there are helicopters that can land on water, carry water(firefighter helicopter),amphibious helicopter,etc...
How do you land the helicopter on Grand Theft Auto Liberty City Stories?
first plan where to land and then slow down your helicopter's speed and press R3 which works for the landing gear and then you can easily land the helicopter.
Can marine one land on water?
No, Marine One, the call sign for the helicopter carrying the President of the United States, cannot land on water. It is a Sikorsky VH-3D Sea King or a newer model VH-60N White Hawk helicopter, both of which are designed for land-based takeoff and landing. These helicopters do not have the capability to float or land on water like a seaplane or amphibious aircraft.
How much area do you need to rope off to land a helicopter?
Depends how big a helicopter.
How do you land a helicopter in red crucible 2?
You just land it yourself
Where does a helicopter land on?
Boats, Helipads and Airports.
What is the thing that helicopter land on?
That is the landing pad
When there is a tornado at a school where does a helicopter land?
The helicopter would most likely land and a field or some other flat area that is relatively free of debris.
Can a helicopter land with out the rear prop?
No, it would spin around and not land properly.
Why do you need the helicopter?
They can pretty much land Any where
WHEN A HELICOPTER APPEARS TO LAND BUT DOESN'T?
It is said to be hovering.
What do you call the place where helicopter lands?
A "helipad" is a helicopter landing pad. The helipad provides a clearly marked hard surface away from obstacles for the helicopter to land.
