Non veni pacem mittere, sed gladium.
Modern aircraft (with the exception of the Warthog and the old B-52's) can't sustain that sort of battle damage...and are ruinously expensive.
Like fine timepieces they are, tick tocking along until hit with flak.
Strong air frames, but...Don't be so sure that this was enemy fire; many of these pics are from aiming point recorders that caught friendlies that strayed into the drop and had a (non-explosive) collision with a bomb on its way down. The damage looks more likely to have been from that sort of impact than from a near miss by AAA, and the ground below looks like it was the target area; any more background on the photo as to the fate of the airplane and its crew?
LOTS of good info here:http://ww2db.com/index.phpAnd this is the link to the Liberator photos:http://ww2db.com/photo.php?list=search&sp=&startRow=0&keyword=&source=all&color=all&foreigntype=A&foreigntype_id=32&dt=&image_id=
