Chugalug 2. You can count a 4th to that...me!
The result of the Chinook flying below SAlt was CFIT. Considering the high value of the SLF the captain should have flown the aircraft at a safe level and if unable to do so should not have descended to low level but turned around instead. Low level increases the risk and should be flown at such levels only if operationally or for essential training. The labelling of manslaughter is harsh because of the ramifications it has for the families of the crew but acceptable to those of the pax.
