A few years ago wdl-aviation used to fly the Bild-Zeitung ( German sun) form Essen-Mülheim (EDLE) to other Airports in Germany. for this they used a Beech Baron or a Piper Senneca.
Well they had this pilot who got strapped in an then they started loding. (They being highly qualified people who diden't bother to fasten the cargo...

)
Well during take off the whole load slipped backwards, resulting with the plan impacting with the ground to the left hand of the runway. Luckily the pilot was not injured...
But round about 3 mounths later same guy, same senario, but this time he was airborne for round about 5-10min bevor crashing on a schoolyard, killing himself! The radio masseges which were recorded were sopposingly not very nice...
Well I do not know how much is true about this but this a story which I was told in my W&B lessons...
Other people, at the club have told a similar story so there must be some truth in it...
If anybody has some more info. would be nice if you could forward it
