News update: Gaganyaan project schedule partially announced in press conference

AIR news (All India Radio) says that ISRO chairman Mr. K. Sivan confirms planned launch of two unmanned Gaganyaan test flights during Dec' 2020 and July' 2021 respectively before manned launch in Dec' 2021.

This info comes from a press conference held in New Delhi, so we can safely take it as an official word and not just casual mission update usually provided during interviews/ meetings which always gets delayed/postponed for very long time.
