Charlie is a bit of a sad-sack, but considering the house flies, has a myriad of conveniences, and can comfortably sleep a dog on the roof, I think his skills as a builder are a hidden Gem . . . or Snoopy is the real builder at which point Charlie's sad-sackedness doesn't come into play.
And I do expect Snoopy is an excellent pilot, at least in his own mind, Sadly, I think the contest has been decided multiple times before:
It would be interesting, however to see what it would take to make Snoopy the victor . . . with a dog house.
