As the thread has drifted into a Chinook one, and the first Wessex is an 18 sqn aircraft, I thought it appropriate to add this bit of nostalgia never seen in the public domain before. This is some A level flying from all crew members which from somebody who does not do Chinooks is quite something.
Who would want to be under that downwash? But I believe that there are 3 individuals on this Fire Watch tower being assembled in Germany in about '88.
