I'm amazed we still have so many Chinooks! It must be because they and their crews are so awesome!
I'll remember to tug my forelock next time I walk into Benson
p.s. Mrs Bas, for reasons best known to herself, loves to see the Chinook fly past our place. Recently, at an RAF lunch, she mentioned this to a gentleman who turned out to be an ex helicopter test pilot and who was delighted to discuss the technicalities of rotary flight; serves her right!
