Wow ! 27 yrs old SQ B744 Capt. Even the youngest B777 capts I've come across are in their mid 30s. Just a theory, but if he was a Singaporean, my guess is that he could be someone well linked to the higher ups. Any idea what his surname was ? Just a theory, so please don't shoot me down.
On an interesting note, I've seen a Asian female FO in her late 20s early 30s flying a B744F. Never seen any other female cockpit crew in an Asian carrier's B744 yet.
