Standard. Happens all the time. Bit dweeby but I know a few guys that do this regularly and with high degree of accuracy.
Lancs frequently pulled all sorts of crazy corkscrew maneuvers (with bombs still slung up) to evade German fighters. Crew members came back with broken arms and legs for the violence of the maneuvers.
Whilst suicide carpet bombing is a great way to ruin everyone's fun really quickly (and thus dweeby, in my opinion) the sharp maneuvers probably aren't that far out of the aircraft's war-time envelope.
The Hurricane's ability to dive with the biggest, baddest and heaviest American steel is more puzzling to me.

Also, if you're trying to mow down lancs in a weeble wobble, you're in the wrong GV.
