Re-Hole in the Hull of OJK, It appears that many posters as always fail to mention that the flaws in the machine are those that are designed by humans.
If it is caused by corrosion then we need to design materials or build machines that do not suffer such effects, carbon fibre perhaps but time will no doubt reveal all the flaws in that technology.
Oxy bottles failing, redesign to remove possibility or remove nessessity for onboard carriage of emergency oxy.
Other speculations that humans who wish ill on others and fabricate harm that is more difficult to engineer out of the human condition.
Random acts of chance well that is the most difficult to control that will be possibly the most difficult to re-engineer.
The pax on JK should feel relieved that they experienced the best of our current engineering and human skills whilst travelling in a machine only dreamed of a century ago.
