I quote the AIS that was available to the crew (I assume from the posts that they landed on 30)..
"Exercise extreme caution when taxing clear of RWY 30 via exit at end of RWY due to unusual lighting characteristic".
What is that exactly? Fifth of July fireworks? A laser show? You work it out.
At the end of the day the crew went for the safe option. No-one hurt. An excellent result despite poor briefing availability. This is a small demonstration of the lack of information that is available on a world-wide basis to professional crews who have to make the best of someone else's poor collation of airfield unserviceabilities.
The fact that is doesn't happen more often is testament to the experienced instinct and perceptive appraisal of the information that is made available to them, often at short notice.
