Cell phones in flight

No doubt, cell phone is a boon to our modern-day living. It helps us to keep in touch with nearest and dearest ones plus in maintaining important communications. But unfortunately the cell phone users often ignore safety codes. Recently, I witnessed in a Malaysia Airlines flight that in spite of repeated requests over microphone, quite a number of passengers continued using their cell phones. Many air-passengers are reluctant to appreciate the risk of operating cell phones particularly during take-off and landing because modern aircrafts are being digitally controlled. The cell phone signals may cause serious interference to aircraft's digital communication network and cause malfunctioning with errors. I would suggest airline authorities to take some stringent measures to make passengers switch off their cell phones as per the airlines safety instructions.
