Planes dont fall apart in mid-air..

Here's one that did (a B-52) (link):

- 187 crashed 1/24/61 near Goldsboro, NC, fatigue failure of starboard wing after fuel leak at high altitude, wing failed when flaps selected during emergency approach to Seymour Johnson AFB, two nuclear weapons separated from the aircraft, one fell by parachute, and the other broke apart on impact

Sometimes, engines ARE designed to separate from aircraft if the vibrations(like an off balance washing machine) are great enough to affect flight characteristics....or so I've heard.

The 767 are new planes. Also the target of terrorist flight training. Short of bird doo-doo on the windshield, what would bring one down, separating two brand new engines from the fuselage?

Nah... not at all:

Then there's the de Havilland Comet, a beautiful jet that had the unfortunate habit of blowing apart in flight due to metal fatigue:
