Bad but there are times when it probably wise. I once watched a BA 747 land at MAN in a very strong crosswind causing wind shear (on 06 finals - as it was before R2), he saw the approach though and landed but in so doing rolled (laterally) after touching down and no1 engine struck the ground. As is was night time there was no avoiding the shower of sparks as the engine cowl struck the ground. Apparently, the flight crew were unaware of what had happened, it was only when the ground engineers started their turn around checks that it came to light. The turn around was scrubbed, engine change required.
