markjoy, that sounds like a lot off fun. i have seen those things on tv. but didnt realize that they still get used.
on the subject off being airsick, there is a book written by a NZ chap, called "flying low" forgotten name off author. but maybe someone else knows, anyway it is about the early days in topdressing and the author taking up flying and spent quit a bit off his early training
. he got over it and went on to topdressing for a career
So dont give up!!
