Overcome current numerous challenges related to delivery Drone

It is now obvious that, Drones are starting to be used to transport packages to customer locations, but there are still numerous challenges to this delivery method such as: limited flight range, theft of unattended packages once delivered, and a lack of delivery network optimization. The new invention by IBM inventors (US Patent No. 9,561,852) can help to mitigate these challenges by providing in-flight drone-to-drone package transfers to extend package delivery range.
