I read about this in the Telegraph at lunchtime. Very sad.
If the inclusion of such threads causes just a few pilots to fly as though the engine may stop, then such inclusion may save lives.
At this time of year, many people are flying for the first time after a winter lay off. Their aircraft have been layed off too.
Lets hope that this tragic news means that others will be extra vigilent when doing checks and be more expectant of an engine failure when climbing out or even just cruising around.
My condolences to the pilot and passenger's families.
