Sorry,don't know.
They sent up flares because the people on Titanic could see another ship close by (the California) but she did not respond to Titanic's CQD messages. (California's wireless operator was in bed because he had been on non-stop since 6am) and the other ship did not respond to Morse lamp (it was too far away. The only other way Titanic could get the other ships attention was to send up flares.
sun releases solar flare, because many hydrogen collides on each other.

The US Navy did not send any ships to rescue survivors. All survivors of the Titanic were recsued by the Carpathia, a passenger/cargo ship.
No. The closest thing to a telephone was the Marconi wireless set. There was one on the Titanic and people could pay to send messages to people they knew. It was very expensive for a passenger to send messages so they were usually very short.
In April 1912, as it was happening (the Titanic crew were able to send out an SOS, which was received by nearby ships).
It is Launch
The Saturn V rocket was used to send humans to the moon during the Apollo missions. It was a large, multi-stage rocket developed by NASA in the 1960s specifically for the purpose of the Apollo program.
They give it to another ship to send it to the land.
