FLIGHT BRIEF

Orb-14 flew to approx. 76K ft and was
recovered from a tree between Big Cabin
& Ketchum, 2 miles north of the Mayes Co.
line. The flight track was as predicted,
but the mid & upper level winds were much
calmer than predicted.

-----

ATV

The ATV, using a Little Wheel, transmitted for
the duration. Reception in the Jeep, also using
a Little Wheel, was good to 15k ft then poor. We
were able to see our vehicles pull up under the
tree it was in at the landing site. Reception at
my QTH using the big KLM satellite antenna was
P1-P2. 

-----

CUTDOWN
The cutdown failed for unknown reasons.
The squib checks ok, but the battery is
down to 3.2v from 6v and it is emitting
a strong paint thinner smell. ???

BATTERY UPDATE

Tue Oct. 26 0800
Upon further investigation of the Eveready
2CR5 battery. one cell was at 3.2v and the
other cell was at 0v. On the 0v cell positive
terminal there are two areas 180 degrees apart
 where there is a light deposit of a grey/brown
film. It apparently emitted something. The film
 did not extend outside the battery package.

Tue Oct. 26 1300
I have been in contact with Eveready and they
have been very responsive and helpful. The gas
that was vented is called DME, Dimethoxyethane,
or 1,2-Dimxyethane, or Ethylene Glycol Dimethyl
Ether, which smells like Ether. It is a flammable
vapor and is non-corrosive to equipment. All
Lithium batteries vent this gas, but in such
small amounts that it is not normally noticeable
except when contained in a small air tight
enclosure. Altitude may have been a factor in
the amount of gas vented. I am waiting for a
call back on that. I was told there is a
company by the name of Gore that makes a
permeable plastic membrane that will suppress
the odor. I have not found them. I wonder if
Tyvek would work?
