Shocked skipper Andrew Flintoff blamed one calamitous hour for undermining England and handing Australia a stunning six-wicket, last-day second Test victory to seize control of the Ashes series.
England were left numb by an astonishing turnaround as Australia bowled the tourists out for 129 and then peeled off the winning 168 runs in just 32.5 overs.
Flintoff's tourists now face the sobering reality that they must win two of the remaining three Tests to hold on to the Ashes they so euphorically won at home last year.
Once again it was leg-spinner Shane Warne who put the skids under England with 4-49 off 32 overs -- 4-29 off 27 overs unchanged Tuesday -- to spark the English side, with the tourists losing their last nine wickets just for 60.
Resuming the final day at 59 for one, England unravelled to 89 for five and the damage was done.
"For four days we played some fantastic cricket but I think it's obvious that today for an hour, that's when the game got away from us," Flintoff said.
"Shane Warne and Brett Lee bowled well and took wickets, and from that we got on the back foot.
"The lads are bitterly disappointed because we gave it everything, but it just shows you that in Test cricket if you have one bad hour it can cost you the game."
It was an ignominious day for England as their first innings 551 for six was the largest ever declared first innings total for a team who then went on to lose the match.
