Yep, that was pretty normal back then
Well remember my first trip to the desert, found the leveled bit and landed feeling a large amount of pride until ....... taxiing in there were these little tins every so often. No one told me they also came in at night
Just the same even though you can construct a rough circuit pattern / levels on the Proline 21 if you choose, it's still a very good effort by the RFDS troops
Probably don't get as much practice at it these days, so well done
