My apologies.
It was a slip of the keystroke - thinking Souls on Board - I guess it's an old term and doesn't really relate to POB - my mistake - hands up - sorry - sorry - sorry
Does it help us understand why a presumably fully serviceable, correctly fuelled, professionally 'driven' 738 flew all the way from IST to land short by 500M and losing 9 of the 138 POBs in the process.
