This is the last major water crossing and I am lucky to have such a great day for it albeit a bit hazy. I have found that after spending long periods of time crossing water you can become a bit disoriented (known as spatial disorientation - the inability of a pilot to correctly interpret aircraft attitude, altitude or airspeed in relation to the earth or other points of reference). Luckily a friend and fellow pilot Ross Willamson (Crowfield Airfield, Suffolk) warned me of this when he saw some of the water crossings I needed to make. This has been really useful as I have been consciously aware of scanning around the horizon, sea, cockpit and not just focusing on one spot, cheers Ross !!
