Can the spheros get back onto the UAV before the end of phase 2?

On the phase detail section of the game manual, it infers that the spheros can only board the drone after all six people were dropped off at the safe zone. Is this accurate?

This is good feedback. We are going to change the verbiage to :: “At any time during Phase 2 the Sphero First Responders can load or reload onto the AVR drone”
