The situation:

The aircraft was originally certified without an electrical
system. It's usually flown with a handheld radio powered by
a battery. The battery is dead. The airport is
non-towered. The wind is nearly 90 degrees crosswind. You
haven't been able to fly in 4 weeks, and if you don't fly
today, you won't be able to get in the air for at least
another week.

Would you fly?
