According to the article,
The first of Boeing's jets, a 707, took off from Paine Field at 6:40 p.m.
and landed at Boeing Field at 7:07. It was followed every few minutes by a
717, 727, 737, 747, 757, 767 and finally the 777. They parked nose to tail
outside the museum in a display believed to be the first such gathering of
all of Boeing's jets in one place.

Not all of Boeing's jets. Just one example of each model!
