SBS7438B doing Sv21 for the past 4weeks or more consistently,
even on weekends. No apparent Sv21 B9TLs went out as of now. Nt
surprising he suspects that. But no need so eager to prove that its
temp perm lah. 
he is too eager on this. Only cameo one day,then ask whether it is
temp perm?
it might be fleet reduction cos Sv 72 schedule is being
revised on 26/5. Or maybe K230 will be deploy on Sv 72 ?
