Is that all it was? That's just a 4-6 passenger light twin. (If you have 6, you can't carry baggage) Its not even a heavy twin. It carries 120 gallons of fuel total. Wow. That's a lot of damage for such a tiny plane. Its essentially a Piper Cherokee VI with a twin engine.
AND if one engine were NOT operating properly, its sounds even more difficult to slam it into a building with wings level. It would not want to fly straight and level.
Sure the hell is.
