Fearless Tower
Touchdown! Greaser!
Complacent is the Mooney I lectured on behalf of ATC who wanted to fly into a squall line at an altitude which would've put him right in the storm.
Dodging thunderstorms or otherwise dealing with them to get around/through a line isn't being complacent if you know what you're doing and are careful about it.
You can dodge the cells in general visually so long as you maintain VMC. The embedded storm bit can be the interesting one. Without real radar (not XM), it's not a particularly good idea.
Ted, not saying I completely disagree with you and Henning - your experience level is much higher than mine, but DAL 191 was in VMC. They could see the storm clouds. And IIRC, they weren't flying through them, they were flying near them.
Different scenario than the sqaul line depicted in this thread, but maybe that is more my concern. While I am dodging the showers that I can see, what is preventing a cloud directly in front of me from choosing that moment in time to kick my butt?
