It is interesting to note that when these accidents happen it is invariably British pilots involved. Are our IMC in Class G rules and mentality to lax and lead is to pushing it in other countries where the ramifications are much greater?
I have known enough pilots from Germany who have taken themselves and their families out in exactly this way. One the them from our airport was especially tragic because he had his girlfriend and her two small children on board. In a Cessna 340 with pressurisation and everything, but he wanted to save a few Euros of Eurocontrol fees by flying VFR from Italy to Germany. He hit the mountains only a few miles from where this one here perished. What an incredibly useless way to die.
And regarding British pilots: Maybe they fly in the (false) assumption that at 1500ft MSL you are safe from both airspace and terrain whatever the flying conditions may be. Inside most parts of UK airspace this assumption may be true, but outside the UK it is only true regarding airspace...
