Thanks for the suggestions everyone. We had a couple of decent meals in town, saw Winter Wonderland, and a bit of window shopping on Oxford and Regent St. I wanted to also see the Design Museum, but Mrs. Expataus was less keen.
I also drank too many flat whites, in and around Fitzrovia to try and stay awake, although having put my Winter coat into checked luggage, the weather did a decent job of keeping me alert as well. Back in T5 and about to head to my next flight, here's hoping the luggage sensor on this plane either works, or has been removed as well.

A pilot's perspective on this would be welcome, but my impression was that the autobrake would be likely both to start first and to do most of the work of deceleration. IIRC, despite all the sound and fury, reverse thrust is a relatively minor contributor to stopping in these circumstances.
And baflyer999's description of the gap between the first and second attempts suggests that the first RTO was at a low speed, otherwise time would have been needed for the brakes to cool.

As you say, would be good to have an expert view.

Yes, on both occasions they announced crew to be seated, we turned onto the runway, full acceleration followed by hard breaking, sitting on the runway for another minute or two, and then turning and exiting the runway. Don't believe the front wheel ever made it off the ground, and everyone got a good jolt each time.

Most airlines teach close thrust levers/brakes then speed brakes then thrust reversers.that being the order of retardation effect.Thrust reversers contribute lots of noise..
Size 12 boots work ok if the rto function is not armed at low speed.
