I had a similar experience a few weeks back returning from Melbourne to Willytown on a Jetstar 320.
Arrived off the coast of Willy at around 5,000 ft, and heard something mechanical being deployed, but couldn't see anything move, I was back around row 19.
Figured it was the gear in an effort to slow down, which we did.
We turned inland and crossed the coast at about 3,000 ft, north of Willy and began to pitch up to slow further when I realised that the Leading edge flaps had been deployed, but no main flaps?
We then turned left again at about 2,000 ft and crossed overhead Willy, still decelerating and still no main flaps!
By now I'm beginning to worry that maybe the boys up front were being distracted by the Hornet activity and had forgotten flaps (not supposed to happen in the computer flown Airbuses) and started to think 'What do you do if you think something is going wrong, and can't tell anyone?'
At about 1,500 ft we turned mid down wind, feeling quite slow and nose high and finally a bit of flap started coming down, so I got out of the brace position and watched the rest of the landing.
The gear actually started coming down on base and more flap was added on final and the landing was completed with a fairly sudden overpitch resulting in a good bounce, which was as suddenly dropped by the deployment of the lift dumpers.
Probably a good thing I wasn't about to have my blood pressure checked at the time.
In their defence, there was a fairly good (15~25 kts) wind blowing partly across the strip.
I guess I've been watching too many of those aircrash investigation shows..........?
