There are telephones already on flights.
They do generally keep the idiots off them as the phones require a credit card.
I suppose that this new system would allow incomming calls.
Maybe there should be an idiot class, lower than economy for t*ats with ringtone and Sms Alert Syndrome. (SAS). Those people that are blissfully unaware that their phones piss people off.
However a Wi-fi system on an aircraft would be a good system and I am sure that I would find it beneficial.
