Before jumping on the bandwagon I'd urge everyone to think for a moment. All this is based on a press item in India, the standards of which make the Daily Mirror appear a pillar of ethical journalism.
The news may contain trace elements of truth (eg. possibly the fight did happen with gear extended), but the very fact that the gender of the pilots is mentioned should raise a flag. I cannot believe that anyone with enough competence to get a 320 into the air would fail to notice a GD situation. There are any number of possible explanatons, as some of the more sober posters have already outlined.
