Just heard this story on the BBC Radio 4. And you will not be surprised to learn that one aspect of the story reported in the
Times of India:
When the plane took off from Paris for Lahore, Ahmed woke up and realized she was going back to Pakistan. She raised an alarm and asked the crew to take her back to Paris. She was told her request could not be entertained and she was asked to stay calm.
Radio 4 said that, when se woke up and realised where she was and what was happening - she kept quiet and did not say anything until she arrived back at Lahore.
Also, there was no mention in the radio report of a sleeping pill. However, I have to say that, irrespective of whether she caused a row or not - a sleeping pill seems likely to have been involved - due to events that did NOT wake her up.
There's an identical and longer thread in Spectator's Gallery.
