[Elecraft] OT: Butane soldering irons

[Al Lorona]

WARNING: OFF-TOPIC
 
 
I carry a butane-powered soldering iron in my Field Day Go-box. Just in case.
 
This FD I had reason to use it. However, I couldn't ignite it. It would sputter and refuse to burn. We were at 7400' (2260 m).
 
When we got back home it worked perfectly. So I guess that these butane torches aren't any good at high elevation?
 
Looks like I'll have to invest in a battery-powered soldering iron for next year.
