Following Anwar Sadat's ascension to the Egyptian presidency, Libya's relations with Egypt deteriorated. Sadat was perturbed by Gaddafi's unpredictability and insistence that Egypt required a cultural revolution. In February 1973, Israeli forces shot down Libyan Arab Airlines Flight 114, which had strayed from Egyptian airspace into Israeli-held territory during a sandstorm. Gaddafi was infuriated that Egypt had not done more to prevent the incident, and in retaliation planned to destroy the RMS Queen Elizabeth 2, a British ship chartered by American Jews to sail to Haifa for Israel's 25th anniversary. Gaddafi ordered an Egyptian submarine to target the ship, but Sadat cancelled the order, fearing a military escalation.
