I did have a mobile phone on 2 June 1994 (and earlier) - and it was about the size I quoted and it also weighed about the same as a housebrick.
My memory is perfectly clear about that day as I was the Duty Contact for 32 Sqn that evening and I was contacted by STC Ops well before the BBC broadcast the news of the crash. I had to re-arrange the entire flying programme for the following day by phone to accommodate the plethora of new tasks associated with the Tragedy. After 2 or 3 hours sleep that night I was back in at Northolt at 0600 the following morning to ensure everything went smoothly.
