If an airliner loses GPS and radio communication, its probably going to crash.
Most pilots would likely decend to find a major highway and try to follow it to a regional hub where there is a class B airport. Assuming they find the field, they've got to navigate through densely congested airspace (with no communication). I wouldn't want to be anywhere near a big city to see the outcome of that.
Of course the impact on aviation would be a small matter compared to the fallout from other impacted infrastructure.
