creampuff, it matters not what the cause of the Jabiru failures actually is, still less that there is most likely a solution.
CASA has decided to put Jabiru and the RAA out of business, it matters not what Jabiru say now. All CASA has to do is delay any further discussion until December 25th then Jabiru won't reopen in 2015.
To put it another way nothing that that Barrier, Polar and many others ever meant a thing. Unless its quashed right now Jabiru is finished, to be followed by the experimental fleet in short order.
