As a confirmed twin driver let me play spoiler here... I am always
amazed at the way we worry about the boogy man -a single over water -
and ignore the true and present danger - a single over land where the
obstructions WILL kill you... It is flying a single over trees and
cities, and junk yards, and power lines, and fence lines, and rocks,
and abutments, that scares the crap out of me... That is why I fly a
twin...
Most water landings are survived and if they die it is from being
unable to stay afloat... Simply wearing an automatic inflating PFD
while flying over water will eliminate the immediate drowning
problem... These are small, comfortable, and not horribly expensive
thanks to the volume of the boating market - unlike airplanes...
