and unless some people are prepared to test out the new technology then
we
never find out what it can do.

Right. They are generally called "test pilots" and trained and rewarded
accordingly. They aren't what the Marketing Dept. refers to as
"punters".

I don't think many flying schools would prosper if they advertised

"Come and train in the latest Thunderbird 1 aircraft, sporting the latest
technology and a great new diesel engine. (Disclaimer: This engine has not
been thoroughly tested. It may stop suddenly on final approach, or during
spin awareness training, or at any time. Also the glass cockit may fail
completely during IMC approaches. These events are completely normal and
WizzBang Flying Club cannot be held responsible for your death if this
happens)"

Great sales pitch!
