Concordantly with the idea of a common direction indicator (heading indicator) synchronising group movement, (magnetic) alignment was more pronounced in groups than in solitary individuals (Hart et al.
"We really just did pretty simple failures, such as air speed, altimeter, and heading indicator. We wanted to look at their process - how they reacted to something that didn't look right," Casner said.
