Heathrow Director, whilst I have the utmost respect for you and your colleagues having flown into Heathrow many times over my 25 year career, things have changed in the aviation world. I guess you are too out of the loop or had a career where you only had the best of things.
Try rarely sleeping in your own bed
a noisy hotel, trying to sleep during the day, throw in a body clock that has lost the plot, meals at odd times and then a long flight overnight in a warm cockpit with lulling white noise whilst heading east towards a bright light that is painful to look at.....just close your eyes, just for a second...just to rest them....whoah..where's that snoring noise coming from.....?
