New Delhi [India], Nov 11 (ANI): A Bangkok-bound Air India flight returned to New Delhi as its co-pilot missed the pre-flight breath analyser test.

The flight had taken off around 1.45 pm today but returned to Delhi after 30 minutes. It is still grounded at the Delhi Airport with passengers on board.

This is the second such case of discrepancy with regards to the BA test that has come to the fore in the same day.

Earlier, a senior pilot of Air India tested positive in a pre-flight breath analyser test and was declared 'unfit to fly.'

The pilot, Arvind Kathpalia, had allegedly skipped the BA test on January 19 last year.

It is mandatory for pilots to undertake the BA test to ensure that they are not in an inebriated state before entering the cockpit. For safety reasons, they are prohibited from consuming alcohol before reporting for duty. (ANI)
