The Rotax 914F2/S1 in my Stemme has never failed to start.Â* That said,
I'm never outside of gliding distance of a paved airport. True, this
limits me some but, should I ever need the engine and it should fail to
start, it'll be a non event.

Could you prepare a detailed study on the reliability of "means of
propulsion" of sailplanes?

What percentage of in flight start attempts are unsuccessful?

Eg: Self launch verses sustainer. Internal combustion verses jet
verses electric. Failure to start verses running out of fuel/energy.
Failure rates of control, deploy and retract systems. Fires and
electrical faults, while flying and on the ground. Recharging and
refueling incidents, etc.
