This reminds me of an optical illusion I observed several times.  First let
me draw you a map of the actual area in Des Plaines, Illinois:

                 |  |          |  |<- Tollway
   |<- 747       |  |         /|  |\ <- Bridge
  /|\            |  +----------|  |-------------------------------------------
 / | \           |             |  |                                    <- (CAR)
   ^     O'Hare  |  +----------|  |-------------------------------------------
         Intrn'l |  |         \|  |/       Wolf Road
         Airport |  |<- Touhy  |  |
                 |  |   Ave.   |  |                North ->

Driving south on Wolf Road, I could often see a 747, DC-10, etc. parked
at a hangar at O'Hare.  From far down the road, it appeared ENORMOUS, (as
viewed under the Tollway bridge).  As I approached the bridge, however,
the relative (apparent) size of the 747 shrank, due, I suppose, to the
increase in the relative (apparent) size of the opening under the bridge.
