"I started building the LEGO passenger plane with my 3 kiddos. Ages 10, 7 and 6. About half way through the building the 7 and 6 year lost focus and were bored. Leaving the ten year old and myself to piece this plane together. We had a great time working together. One piece was not cut the right way but we made it work. The step by step instructions were easy to follow. Overall is was a great project."
