In these days when 90% of the population are taking photographs of themselves every ten seconds and documenting their every bowel movement online it seems to me that writing a straight forward letter is to be applauded.
Over the years I have received, via my company, many letters like this and its what used to be called, in more courteous times, A Letter of Introduction.
This letter would normally give the writer a visit to the flight deck or a chat with the crew at some stage of the flight. Prior to 9/11 I would also probably offer a cockpit jump seat for take-off or landing. It was an opportunity for someone to gain an idea of what was involved in operating an airliner and for the crew to hear someone else’s life/occupational experiences. It would also in a few cases lead to future employment of the writer.
The letters would come from general members of the public, teachers, firemen, atc staff et al.
I say well done that man.
