I'm lacking statistics to back this up, but I recon that on an average long haul flight with 300 passengers at the very least five phones will remain on during that flight - without complications. Lets face it, the possibility of UHF interference is a faint one. If anyone was to take this properly serious there should be someone with a cell phone detector on board walking the aisle after boarding. People know about the ban, people have heard the announcements a thousand times, people forget that their telephone isn't turned off... WHBM made an honest mistake, whats with the lecturing? My oh my.
