Thanks to Heathercollins0614 for this inspiration! I used 14" round pan, and 2, 13 X 9 pans to cut the pointy pieces, and the cockpit, and a 6" round pan (cut 1 inch high) for the upper deck. All chocolate cake, All buttercream frosting. I ran out of time so I didn't get to "Viva" the smooth sections and the sides. I would have liked to have done more detail on the sides too. Still, my 7 year old grandson (and his guestsand their parents) were very impressed. I had trouble molding the radar screen, the guns and turet out of Royal Icing, so I improvised by using 2 cut straws in playdoh - dried and spray painted. The radar screen was a new suction cup, spray painted and inserted with a toothpick. The cockpit windows could have been better if I didn't have such a shakey hand. I turned 68 on Friday.....not as young as I used to be!!
