Nice review, and it looks like a really nice set with a good mix of builds. The fact that I read the entire review without looking for the price speaks volumes for this in my opinion. The planes look good and I cannot see anyone from any age group who buys this not giving all three planes at least a quick test drive round the living room. One to add to my list.
Since around 2000, the Lego Group has been promoting "Lego Serious Play", a form of business consultancy fostering creative thinking, in which team members build metaphors of their organizational identities and experiences using Lego bricks. Participants work through imaginary scenarios using visual three-dimensional Lego constructions, imaginatively exploring possibilities in a serious form of play.
