Interesting comment by the passenger that the announcements were clear. We had to turn around a few years ago from FRA in a A340-600 due to a sticking under carriage and the information provided was excellent as was the way the whole situation was dealt with.
At the risk of spearing off on a tangent, I've never flown a "dumper"; what do Pruners think of this comment on AvHerald on this incident:
you never ever dump fuel in a holding pattern. Guess what happens when you fly through your own fuel cloud in the holding.

Here is what Boeing says:
Fuel Jettison
Fuel jettison should be considered when situations dictate landing at high gross weights and adequate time is available to perform the jettison. When fuel jettison is to be accomplished, consider the following:
• ensure adequate weather minimums exist at airport of intended landing • fuel jettison above 4,000feet AGL ensures complete fuel evaporation • downwind drift of fuel may exceed one NM per1,000feet of drop • avoid jettisoning fuel in a holding pattern with other airplanes below.
