Wow, just had a look at the Canberra H/L Area chart, the 5308' obstacle is about 24nm south of the field
. Looks about just right for a CFIT with their(incorrect) right hand hold on CCK. Can't believe no-one picked up on the 2 limits(crosschecked/reasonableness), surely they've seen this place in the day and know how 'hairy' it is to the south.
Close call, hoss
