Statistics for Expendable Launch Vehicles (1988-2015)

¹   Criteria ensure avoidance of triggered or natural lightning

²   Criteria specific to user operations and capabilities such as surface wind to ensure tower clearance, excessive cold temperatures for vehicle performance, upper-level winds for vehicle loading        and steering, etc.

^1,2 Scrubs for Range and user-specific criteria are sometimes violated simultaneously, i.e., the data sets are not mutually exclusive
