In addition to the thermal stresses of a cold water environment, when a helicopter ditching occurs, there is a high probability of inversion, followed by an underwater egress.
In the maritime environment, a Landing Helicopter Dock such as the USS Wasp wouldn't be the capability of choice for covert surveillance and reconnaissance tasks in unchartered territorial waters; and a destroyer wouldn't be the most suitable option for anti-mining operations.
Ultrasonography is also better than auscultation in noisy environments, such as helicopter retrievals.
