Classification of milestones
Milestones are classified by the type and importance of the event. The type of event provides an objective view of the context for the event whist the importance is a subjective view its importance to VTOL history. Both are determined by the contributors to Vertipedia but the latter will always be subject to discussion and debate, which is welcomed through direct participation in Vertipedia or by contacting the Vertipedia team.
