A report of hydraulic failure from an Air India Express flight, causing mid-air scare and prompting the airplane to hold a subsequent circling pattern for nearly two hours, has left many wondering what actually hapepened in the interim.

An express train, at 75 kmph speed, hit stationary goods train on Friday in Tamil Nadu as it entered a loop line instead of getting into the main line, railway officials said, adding that a number of passengers were injured and a coach caught fire.
