On a side-note, 161 was probably the only service that had used
every major type of ADD you can think of at a single given point in
time.
Definitely no other service has that distinction.
The simple reason is that you need a AMDEP/HGDEP
combination....and a programme specially written for Tridents to
ply. The last was not compulsory in fact. The first couple of times
Tridents did 161, they just used a plastic desto on the
dashboard.
If only K310 will cameo on 161...
Cheers.
