It was BA.
I have no way of knowing whether reverse was deployed; it didn't sound like it but then I have no idea what idle reverse sounds like in an overwing seat on a 744.
Since they were used considerably in descent (through flap extension) until just before gear down, I'm assuming they were serviceable a few minutes later.
I thought at the time that perhaps given their late use the crew were distracted and didn't arm them. Given the long runway (4000m) with a RET taken at about 2500m it certainly didn't get exciting.
Just curious, really.
