Waiting

So we haven’t taken off as we had to taxy back in as there was a strange smell and loud rumbling! My first thought was an air conditioning pack packing up! Seems I was right! It’s being isolated and we should head off in an hour as there is redundancy in the system. Virgin crew excellent and Captain keeping us in the loop throughout with briefings. He has walked through the cabin to answer any questions while the engineers work. Good captaincy skills! Poor soul had to put up with my questions regarding if the other one failed and if we had to descend would we have fuel to reach a diversion etc! Sometimes knowing too much makes me a poor passenger. Anyway should be only a couple of hours late back to London.
