You are Jack Phillips, the senior wireless operator aboard the RMS Titanic. At 11:40 PM, the ship struck an iceberg. Captain Smith has just ordered you to send distress calls. The Carpathia is only 58 miles away, but they must receive your message in time.
Transmit the correct Morse code sequences for each distress message. You have limited time before the ship's power fails. Each error increases the urgency level and delays rescue.
The fate of over 2,200 souls depends on your skill with the wireless. Can you send the SOS in time?
