The saddest part of this whole thread is that I am not in the least bit surprised that Fleigenmong's company is introducing a safety policy to use the coffee plunger. Thats "ops normal" in Australia's business culture today.
No matter how enthusiastically the lawyers pursue this matter or how much the regulators / business colleagues / local aviation fraternity may duck n dive, at the end of the day one fact remains - one young man climbed into a plane expecting the time of his life, not the end of it.
