I went through that phase in the third or fourth grade. The steps to my family's basement was papered with side-on drawings of planes. I don't know if my mum saved any of them, but she framed another drawing I did as a kindergartener (about 1982) that turned out to be kind of eerie after 9/11.
After a trip to NYC, probably across the Veranzano Narrows bridge, I drew a panoramic view of Manhattan from the south with the WTC and Empire State Building featured prominently in the skyline. As a detail, I put British Airways jumbo jet in the sky about to fly over the twin towers. I certainly didn't think about a jetliner crashing into the towers then.
I think we must have been picking up my grandmother at JFK
, and apparently the whole experience made quite an impression on me.
