I have used foam core sheets to construct high altitude balloon payload boxes for many years. They are inexpensive, lightweight, and very durable. It is easy to cut ports and holes for cameras, instruments, antennas, and wires. And it is no great loss if they are damaged during recovery.
An excellent description of foamcore construction techniques by Mike Manes (W5VSI) is available from EOSS. http://www.eoss.org/onlinepubs/construction/foamcore/foamcore.htm This is where I learned from.
Here, I would like to describe some ‘features’ included in our/my construction. Recently, I’ve begun including a back door to aid in manipulating and connecting wires and hardware in the box..

A recent blogger, alleging to be a Christian, but apparently wise in the ways of the world, wrote that among several important Christian teachings he would change, is the idea that Christianity is the only way to God. It is valuable for us to remember, especially during this Lenten and upcoming Easter season, why Christians believe Christ is the only way to reconciliation with God, and that there is no other way.
