WebPilots can't see ash clouds at night. Also, ash particles are too small to return an echo to on-board weather radars on commercial airliners. Even when flying in daylight, pilots may interpret a visible ash cloud as a normal cloud of water vapour and not a danger—especially if the ash has travelled far from the eruption site.
