This is one in which we had our first example
of poor flight planning. They scheduled our
MSC-10 experiment so that it actually confl i cted
with some Horizon Scan Tests that we had to
make. And since our Horizon Scan tests were
being made in conjunction with the platform,
which was only going to be up for a limited
period of time , we had to interfere on the

working on the Horizon Scanner Check. Anyhow,

indicator.
Didn't we have ten series? I t hought we had ten .
I 've only got ei ght indicated here. Oh, yes,

have eight recorded here, and a final one

We should have 9 1/2 runs, and only nine were
