Historical note - The Wright J5 engine was a marvel of reliability in it's day.
In 1927 it got Lindbergh from New York to Paris without a cough or a splutter.
And in 1928 three of them powered the Fokker FVIII/3M with Kingsford Smith, Ulm, Warner and Lyon across the Pacific from Oakland to Brisbane.
The great engine man of the Wright Corporation who saw to the health of every donk was revered by many many airmen and women. Cecil Maidment (known as 'Doc'), was his name.

On 19 July 1909, Herbert Latham took off from Cap Blanc-Nez, very near
Sangatte,
[28] but after only 8 miles (13 km) his
Antoinette IV suffered engine failure and Latham had to
ditch in the Channel, thereby performing the world's first landing of an aircraft on the sea. The undamaged fuselage remained afloat, so he lit a cigarette and awaited rescue by the French torpedo-destroyer
Harpon that was following.
[29] After recovery of the aircraft, the engine was examined and a stray piece of wire was found inside the engine.
[19] Levavasseur stated that the misfire was caused by this wire.

A widely circulated photo of Latham astride his ditched plane, casually smoking a fag while awaiting rescue, is one of that era's most evocative.
Apologies for this digression from the actual subject under discussion.
There is a well known ferry pilot based at Bankstown who has ditched several times. He has had rafts fail to inflate. He believes something like one in ten
are defective.
