There may be times your order is canceled by Zipline. This can happen for a number of reasons.
Weather situations make it impossible to fly.
Technical issues with the fleet or supporting systems make it impossible to fly.
Events impacting the airspace prevent Zipline from flying.
Regardless of the reason for cancelation, Zipline will not charge you for your order and any payment authorizations during order placement will be released in 24-48 hours.
