Looking for pictures of motorglider failures

I remember an engine that would not extend caused by a spark plug wire stuck to the muffler! Apparently the engine had been retracted without a sufficient cooling period and spark plug wire came to rest on the muffler and melted the insulation that turned to glue when it cooled down! Oddball malfunction for sure. Also heard rumors about pilots forgetting to add oil to the fuel in 2 stroke engines and another guy that accidentally added oil twice to the same batch of fuel. Then there was the pilot that leaned out his engine for peak power and melted a cylinder on takeoff. Seems to me that electric motors are the best way forward, but self launching with a motor in the nose gives very little prop clearance. The JETA looks promising.

HERE https://www.youtube.com/watch?v=Puia_yQxir8&feature=youtu.be is an example
of a jet sustainer failure to start.* Good glide path control, but I thought he
may have waited a bit longer than required before dumping his ballast.

No one has mentioned jets? They can be unreliable to get started, and

Interesting, I've heard of numerous failures to start and failure to climb,
but not uncontained blade failures or engine departing AC...

I'm pretty sure that qualifies as a self-launcher!

Motor in a sailplane = a complicated abomination, ......

An efficient light power plane utilizing sailplane aerodynamics = beautiful engineering.,,,,

Look at an FES sailplane - simple. Much simpler than a towplane, and much easier
to schedule when you need a launch. I was part owner of a towplane for years, and
it caused me more grief each year than the self-launcher I now own. And then there
are the avoided retrieves - simple and priceless!

Are we really having this conversation after all these years, with 80% of the
gliders going out the factory door with an engine?

I think this may be what you're referring to?

That is PRECISELY why we're having this conversation.
Looking forward to your contributions,

Thats the incident butI have see more photos one was of a blade
impacted with a wing still I insintue

Not part of the accident report, but here are some additional photos of the hub failure accident mentioned. Kudos to the BGA and their mag for better coverage of such events and remedies. I believe this is the same one regarding the G-SAXT Duo?

Prop blade punctured fuselage, dented fuel tank and restricted
aileron movement. It nearly took out the brakes as well. The prop
had flown 38 hours

Missing blade

The flight manual says to check for cracks in the hub every day. This
is what a very badly cracked hub looks like.

There are photos I will try to put a link in.
