Remember when you could smoke on planes? Neither do I. But the constantly lit "no smoking" signs on every flight are a reminder of the the good old days of airborne lung cancer. Sadly, these historic signs are being replaced in many European planes with "no mobile" signs to coincide with a new satellite based plane-only phone service.
The no-mobile signs will be lit on take-off, when all wireless devices should be turned off, and then turned off when cell-phone calls are allowed.
Air France is switching the signs first, to coincide with their new satellite-based cell phone service, followed by the U.K.'s BMI and Portugal's TAP.
