At first, all the passengers boarded the plane and took their seats. When the plane was ready for takeoff, the pilot came over the intercom, greeted the passengers and asked everyone to either switch off the phones or use them in an ‘airplane mode', which shuts off phone transmissions during the flight.

I quickly turned off mine and was really surprised that there were still people who refused to follow the rule and had a confrontation with a flight attendant.

I know (as I read some articles dedicated to this topic) that this may not be so critical an issue when the plane is already at cruising altitudes as there's no direct evidence of mobile phones or other devices interfering with aircraft systems, but it's really important during takeoff and landing phases because of its possible interference with ground networks, which is dangerous. You know, there's also no proof that wireless devices do not cause any problems, and I'm sure that the signal of the phone does interfere with navigation instruments and can cause instrument display malfunctions. So even during the flight I kept my phone and other devices turned off 'cause I didn't want to be responsible or share responsibility for a crash.
