From Reddit Recap of the Elon Musk and Martin Halliwell press conference with lots of new info, March 31, 2017 (presumably not related to April fools day in some time zones?)
Fairing and future second stage recovery
- Payload fairing LANDED SUCCESSFULLY. Fairing has thruster systems and steerable parachute. Was just shown pic of intact fairing floating in ocean.
- Upper stage reuse is next.
It says "systems" (plural). Does that mean that each half of the fairing use a thruster post-deployment as part of a recovery effort? If so, how are they used?
