BBC journalist Max Pearson, experienced a personal tsunami of sorts when he suffered a heart attack on board a Singapore Airlines flight bound for London.

Pearson, who had flown in from Tokyo to Singapore after reporting the Japanese Tsunami was taking a connecting flight bound for London.
Left with no choice but to endure the 14 hour flight, with his life literally hanging in the air, Pearson was rushed to a hospital after the plane landed at Heathrow where he underwent emergency surgery.
Pearson survived the attack, but the lack of immediate medical attention which is crucial after a heart attack, undoubtedly caused irreparable damage to his heart. He is now considering taking legal action against Singapore Airlines.
