Watching the F15s and F16s perform in this manner isn't all that
interesting as the maneuvers are all well within their flight
envelopes.
However, I would pay good money to watch an RSAF fly-past that
included an E-2C or KC-135R doing loops, barrel rolls,
vertical climbs and simulated strafing runs, though.

This is Singapore leh....it isn't like the USAF where they really
show what the fighters can do.
I've seen an RSAF KC-135 flying at about 200 feet above
sea-level though....now that's really cool.
