Two Britons were among the 19 people killed when the balloon crashed Tuesday near the city of Luxor. BBC tweeted: 19 tourists are believed to have died in a hot air balloon crash in Egypt.Have you tried something you wouldn't normally on holiday? #r2vine Steve Berry parodied: "RT @BBCRadio2 6m Jews were annihilated as part of Hitler's Final Solution.
