Just to add to TTNav's post. Indeed it was as he said that the seat was only fitted as required on the K1s. However on the K2s it was the reverse, only being removed infrequently to accomodate the astro stool.
Windows were replaced with solid panels on failure, but some were also refitted to accomodate a camera during Op Corporate.
I didn't mention in my earlier post that the nav rad's seat was removed in the mid 80s, with the nav plotter's seat being modified to run on rails so that he could slide into the nav rad's positon when required. The AAR panel was also moved closer to his position.
Regards, ex K2 Crew Chief
