The mixup of #19 and #20 is the least of the problems with this diagram. Events on the straightaway are transposed (apparently) to in front on the stands. It badly needs a "not to scale" notice. It ignores the fact that Levegh's car didn't just crash into the barrier and burn where it hit. It left the track on the straightaway, hit a wall to the side of the spectator plaza, disintegrated, and shotgunned the standing room spectators with parts, including the engine, front axle and wheel assembly, and airbrake, to a depth of 100 yards, more or less. This is vital to understanding the disaster, and completely missing.
As an example of bad reporting this may have a use. To explain the event -- none at all. Andyvphil (talk) 15:55, 11 March 2015 (UTC)
