In looking at your blog and being amazed at the quality of model building by your contributors, and I exclude my own clumsy efforts, I am reminded of how building models was once considered a suitable hobby for kids.
Back in 1959 I made my first cross Atlantic flight from NYC to London in a BOAC DC7C prop aircraft, a grueling 11 hours. To pass the hours BOAC gave the attached to kids to entertain themselves.
How this was to be done without tools, glue etc didn't concern BOAC they provided them and that was it.
British Airways carries on this indifference to passengers, luckily flight time is less now.
So for your in flight entertainment, pre SST, try making these models with your bare hands!
REMEMBER: You are someone special to BOAC (Edward Scissorhands with a glue pot for starters)
