Nikon 1 V3 Hodgepodge | Martin JRM Mars Dropping Water

Nikon 1 V3 Hodgepodge | Martin JRM Mars Dropping Water  The Martin JRM Mars flying boats are the world’s largest flying boats ever flown operationally.  Although seven were built, only two remain flying, the Hawaii Mars JRM-3 pictured here and the Philippine Mars.  They have been refitted as firefighting water bombers carrying 7,200 gallons of water.

This Martin JRM Mars is dropping 7,200 gallons of water on runway 18/36 at AirVenture 2016.  You might ask: how do they get the water?  Well, the Captain lands on the water normally, but keeps the the aircraft “on the step” at  60-70 knots. The Flight Engineer controls the power to keep the aircraft “on the step” and selects the scoops to the “down” position to inject the water into the tanks at the rate of about a ton per second.  The 7200 gallon pickup time averages 25 seconds.  When the tanks are full, the scoops are raised, takeoff power is applied by the Flight Engineer and the Captain makes a normal loaded takeoff.  Pretty slick!  Unfortunately water landings are not without risks.  This Hawaii Mars JRM-3 flying boat sustained some damage to the hull when it was scooping up water on Lake Winnebago.  One of the scoops hit something hard that was submerged in the lake.

The Back Story  This image really shows the versatility of the 30-110mm lens on the Nikon 1 V3.  As I was walking toward the warbird area at Oshkosh, this big bird flew over to demonstrate its firefighting capabilities.  Luckily, the 30-110mm was on the camera instead of the 70-300mm.  It enabled me to quickly capture several images as the Mars flew closer. I started panning before it flew through the smoke and kept the hammer down well through the water drop.  Remember, 55mm turns into 148mm on the Nikon 1 V3.  For more information and images on using the Nikon 1 V3 for aviation, see Nikon 1 V3 for Aviation | a 7 Image Story.   Note: I post an image everyday at hankconrad.com.
