Elvis the Water Bomber
One of the big Choppers standing by down under for water bombing of bush fires is called Elvis.
Elvis has a huge proboscis which it can lower into a water source on the hover and rapidly take aboard lots of water.
The proboscis is longer than 30 feet so that no onboard pump would be able to do the pumping.
At sea level a vacuum can barely support a 30 feet column of water.
The proboscis has a bulbous end which has to be the housing for an enormous high volume pump of some sort - possibly hydraulically powered.
Does any one out there know anything about the pump?
