Icing on the ground has the problem of being over larger areas than can be
handled by airplanes equipment.  Airports in areas prone to this have
deicing areas where they can wash down the plane with ice removing
materials.  The problem is then the time between the deicing and taking off
so they can get above the problem.

When they added a new runway to Minneapolis St Paul International (MSP),
they also built new deicing pads at the taxiway ends by each runway.  That
way, they can do the deicing after planes do any waiting on a backed up
taxiway and shortly before they get in the air.

Public TV had a special on about a crash of a British jet that ran into
another while taking off because the pilot (who happened to be the chief
training officer) was really intent on getting home after the airport had
been shut down due to weather.  He ended up getting onto the runway without
proper clearance (ignoring the copilots complaints about the flagrant rule
violation) and hitting a plane that was landing.
They discussed the change in the hierarchy policies that came after that so
that the removed the "chain of command" attitude between the two pilots and
made the copilot into additional eyes and brain power for the pilot instead
of just a back up flunky.
