I take it the 21mill has been invested in upgrading / renewing the 'old' terminal on the North side of runway at Embakasi and NOT Eastleigh as suggested by someone earlier ?
FWIW I attended the opening ceremony of Emabakasi in 1958 as a ( very ) young man , some of my Dads black and white photos of the occasion show some interesting aircraft .
We thought the terminal was the most wonderful building we had ever seen !!
Not a security guard to be seen , seeing someone off meant strolling out to the aircraft steps with them . Halcyon days indeed.
