Billionaire Harsh Goenka criticised Hotmail Co-founder Sabeer Bhatia for his comment on Air India plane crash in Gujarat that claimed about 240 lives. "Do you really think fourth largest economy...should still be having plane crashes due to systemic failures? Time to question what truly makes a nation great," Bhatia said. "Tragedy strikes. Social media vultures circle. Disgusting," Goenka replied.
