Wow. Dale, Best wishes for a full recovery!

Sam (et al.) thanks for the updates. It is good to hear that Dale is
okay. I too am curious as to the cause. We use H2 and H2/O2
balloons frequently. I have loaded them in my mini-van to transport
to local elementary schools. I have never had a problem. It would
be good to know if and how we need to modify our safety protocols.
