Major failure is any loss of life, unplanned destruction of the craft or significant collateral damage.
Only flights above 50km with paying customers count.
@CodeandSolderJust to check, if for whatever reason a flight doesn't go above 50km but there is no loss of life, loss of craft or collateral destruction, that flight wouldn't cause this market to end but also wouldn't count towards the total number of flights?
@ElliotDavies actually I cannot think of any obvious way to cause it without causing one of the other two, but in general destroying a significant amount of other people's stuff by accident in relation to their operations
