See the bottom. Other than the first line, it's the same on our
release for public flights.

Without signatures of spouse, both parents, family pets, it may not be
worth much more than the paper printed on other than we expect that the
signator was of sound mind and undertook the flight with the reasonable
expectation of returning safely. We also expect that we operated
within the limitations of the FAA regulations and will defend our case
thusly. Doesn't mean it wouldn't stop a lawsuit in the event of an
incident. Likewise, we expect that to be defendable, we also expect
someone to go for the deep pockets.
