There is always an active discussion on the merits of various GPS systems. Four fine aviators took off from a well known southern airport, grossly overloaded , straight into a CB, The aircraft, C172 had a skymap GPS and they also had each a handheld GPS. They climbed to altitude, into the CB with the stall warner going. But they flew on and it wasn't an accident. Comment afterwards, "didn't see the weather....stall warner always goes off on this aircraft"
How was the GPS detrimental to this incident? Did they actually say "I didn't see the CB because I was staring at my GPS"? Don't get me wrong, I'm not trying to belittle the incident, but it sounds like the GPS wasn't the real cause. Taking off in an overweight A/C and flying into a CB is just poor airmanship.
