[net.sf-lovers] 'Not Final'

Heck.HDSA@sri-unix.UUCP (08/12/83)

There is an old short story called 'Not Final' by Asimov (I think) which
deals with the use of a force field for entry into and exit from the
Jupiter atmosphere. (The story deals with a scientific 'proof' that the
field is impossible ...)

I'm told there is a sequel to this. Anyone know the title and where it
was anthologized ?
