so rapidl y. It wa.s tremendous. It looked like one of the
autogenous lines ha.d been cut. I guess it was cut with a
pyro, a.nd it was really bending and this was causing it to
translate as well as rotate. And in order to stay with it,
I was having to use quite a bit of fuel; although it was
certainly a nominal task. I also went through several con
trol modes switchings. I sta:rted out in PULSE and I could
not get around fast enough, so I went to DIRECT a.nd then
slowed it up in RA.TE COMMAND. Slowed up the direct rate I
was using with RATE COMMAND, a.nd left it in RATE COMMAND
without using the h&nd controller for a while. Finally
went to l'LATFOBM. When I went to PLA.'f.E'OHM~ we had been off

primary station. The UHF was outstanding.
