Oshkosh Royalty - Hawaii
Mars
'It's aviation royalty':
World's largest water bomber plane with a 200-foot wingspan hits the market for
$3million - with fans paying $125 just to see it up close!
- Hawaii Mars is the world's largest water bomber and dubbed 'aviation
royalty'
- US Navy built Martin Mars model as troop and freight carriers in the 1940s
- They were later converted to seaplanes with an ability to carry 7220
gallons
It's the world's biggest water bomber - with a 200-foot wing
span wider than a 747 jumbo jet and the ability to carry 7200 gallons of
water.
And now it's up for sale.
CNN reports that plane buffs have
been shelling out $125 each to view the plane up close on a lake in
Oshkosh, Wisconsin, where the Experimental Aircraft
Association AirVenture air show is being held.

THE MARTIN MARS: THE
STATS
- Only six Martin Mars plans were ever made as part of a US Navy
program in the Second World War.
- They were supposed to be long-range troop and freight transport
but were converted to water bombers.
- It is the largest flying boat ever operationally -
- Its height is 38 feet while it is 120 feet long and has a wing
span of 200 feet (similar to a commercial 747 jumbo
jet.
- The plane can carry 7200 gallons of water and travel close to
the water at about 80miles/hr.

According to the EAA, the plane is
the last of its kind after only six of the Martin JRM Mars seaplanes were made
for the US Navy during the Second World War.
They were built as long-range troop
and freight transport to fly between Hawaii and the mainland United
States.
But they were later converted to
water bombers and given the ability to carry enough water to cover 4 acres of
land in a single pass.
'There aren't many airplanes that
have never been to Oshkosh, but this is one of them, so this is both literally
and figuratively a huge addition to this year's lineup,' said Rick Larsen, EAA's
vice president of communities and member programs in a statement.
'Among flying boats, only the
legendary Spruce Goose is bigger, but the Martin Mars is the largest ever to be
operational on a regular basis.'
The most frequently asked question
regarding the Mars is How do they pick up their water?. This part of the flying
operation is, perhaps, the most demanding in terms of teamwork among the crew.
The Captain executes a normal landing, keeps the the aircraft 'on the step'
and allows the speed to decrease to 70 knots.
He then passes engine power to the
Flight Engineer and selects the scoops to the 'down' position.
The ram
pressure for injecting the water into the tanks is such that the aircraft is
taking on water at a rate in excess of a ton per second. To account for this
added weight, the Flight Engineer must advance the throttles to maintain a
skimming speed of 60-70 knots to ensure the aircraft remains on the step.
Pickup time is, on average, 25 seconds. When the tanks are full, the Captain
will have the scoops raised, call for takeoff power from the Flight Engineer and
carry out a normal loaded takeoff.
Once airborne, the foam concentrate
is injected into the water load (normally, 30 US gallons of concentrate into the
7,200 US gallon water load) where it is dispersed and remains inert until the
load is dropped.
Once dropped, the tumbling action
causes expansion which converts the water load into a foam load. This process is
repeated for each drop. In other words, this vital team.
The plane's owner, Wayne Coulson,
reportedly said he had decided to put the plane up for sale after the
governments of British Columbia and Alberta did not offer his firm contracts
during the latest wildfire season.
His other plane is the Philippine
Mars, also out of the Martin Mars fleet, and the price tag for each plane is £3
million each.
'Hawaii Mars has reached the end of
its career,' Coulson told CNN.
'It's now time to reinvent it into
something different than what it is.'
'We're going to be very selective
on where these airplanes go. They're aviation royalty.'
