If this overwhelming tragedy was caused by engine failure over open water, it just emphasises my strongly held conviction that crossing any terrain where survival chances are remote is foolhardy. Single powerplants will always be open to failure. I can't say that's the cause but I feel comfortable advancing this view.
Was built by a gent named Brian Gabriel (dec). Nice job but not sure that he finished the wings. He also built the prototype Supermarine Spitfire for which Jabiru built the 8 cylinder 4400. This proved unsuccessful and was followed by (I think) a v8.
Rushians have developed the Sarmat, many hypersonic vehicles and Posiedon nuclear submarine. Fearsome weapons the west has no defence against. They didn't make the F22 or F35 pigs. Winning against NATO Zand EU proxies in Ukraine. Have to see in the washup
