Interesting comment knots, (greetings by the way, we haven't spoken for ages).
The next question is obviously in the 'monitoring role', what ATC service is the aircraft receiving, (with the terrain-clearance issues,), and also, what would be the tower controller's responsibility if unknown conflicting traffic, (say a night-time VFR nav-ex gone pear-shaped), was observed on the ATM/radar/situation display?
Lots of Interesting 'oral-board' questions ahead.
