Believe they are rehearsing for NDP. Manage to see 2 apachi flew
right outside my window from the direction of Kallang after the
first burst of planes flew past. Really mean looking machines. A
few minutes later, saw 3 F16s doing some tight turns towards and
over the skys of Kallang stadium. (partially blocked view)
Every year, in these couple of months before NDP, no matter kallang
or Padang, they will do such high power flying over my area few
times a week. Used to it already. Other times, just the normal
landing pattern into Paya Lebar where the engines seems to be
running mostly in the minimal mode. zzzzzzz
