Mr bernoulli,
I was confused as to why you didnt appreciate the need for mobile phones at work. Then it became clear. "twenty" years in the military" and working for "one of the worlds biggest airlines"That would explain your fragile grasp of the reality of work outside those two lofty spired institutions. Especially if they were the RAF and BA respectively. Both giving rise to Marie Antoinette syndrom. (re Lancet issue 210 2001, The pitfalls of grammar school, The raf, and institutional airlines on the Phsyce of self obsession. A paper by Dr I. AV. A. Chip)
In the real uncosseted world of avaition, mobiles are essential.
