Hi Byrden

Inotice you keep falling back on the philosophical argument as to impossible.

In the literal sense you are correct...but then your argument is more suited (as is the theme)to an existential forum rather than a tank one.

It appears that the use of "impossible"by the TIger people is of course logically incorrect but remains colloquially correct in that it was "impossible"to efficiently drive th etank (if at all)with your head stuck out the top and your spine twisted in illogical positions.

As Isaid, it possible to drive a car with your forehead on the pedals but no one in their right mind would argue with the colloquial use of the term "impossible"in the context of describing the practicality of the action.

Ireally think you are stretching the point by continually falling back on "but you said imposssible" when we know its so impractical as to be the absolute exception rather than the ruke.
