To be clear,=C2-Ian Rickard's very useful=C2-drawing is not
definitive to all variants; earlier tanks have a lesser volume
, and the very first few were quite different and larger v
olume. Some of the latter may have been replaced during the
build.=0A=C2-=0ADuncan McF.=0A=0A=0A=0A=0A-----Original

wi Mod=0A=0AFred et al,=0A=0ABack in 2010, Ian Rickard
produced this excellent drawing (attached) of the Europa tank
. This indicates that the material is medium density polyethyl
ene, flourine treated (the process that makes epoxy stick so
well to it). Ian has indicated when and where various change
s were made over time.=0A=0ANigel=0A=0A=0A=0AOn 27/0

Apropos to this thread, it would seem to be of value if
we could track the kit numbers and the accumulated flight ti
mes of those tanks which have failed, as well as any other
aspects of the failures which may seem pertinent such as
ambient temperatures, long-term storage while empty, etc.=0A=0A
