Craft looks in reasonably bad shape. I suppose its got to do with the fact that it is an ATR. Likely wouldn't have happened with larger birds - I came in from BLR to MAA yesterday, on 9W, and things were fine (though I must admit, we were delayed because another airline was stuck on the main runway and had to be moved which took the best part of half hour). In any case, Mumbai isn't generally wet this time of the year, though today they had light showers.
