My favourite airshow moment was on EWR-SIN when passing by the north pole the plane symbol was spinning around and around - I guess it couldnt get a handle on the bearing!
I also like to leave it on when sleeping so when wake up I can see if it is worth waking up properly or trying to get back to sleep.
Landmarks shown from NZ on the long haul routes arent nearly so interesting. Too much water around so get x-thousand kilometres to Hawaii, some hours later it is still showing x-thousand kilometres to Hawaii!
