1. It was SQ
241!
2. Normally when they pass my window landing on runway 16R they're around 1000ft. But as SQ241 was coming down its Rolls Royce engines were much louder and then I saw it increase its altitude, and deviated slightly from the normal course to landing. It then made a right turn. Quickly flicked to Flightradar24 and saw that as SQ241 was applying power for a go-around, Regional Express flight 473 was taking off.
Would this analogy be correct?
