Smudge, The switches in the fingers of the gloves was CADS. The last version I saw had a weather girl type switch which fitted under a flap on what was the HAPLSS Gloves. (HAPLSS was the High Altitude parachutists Life Support System which included thermal clothing and O2)
What Doug showed was the Military Tandem Tethered Bundle.
The Canadian tube was a cardboard tube (concrete pillar mould) with wooden ends. It came down under a drogue till a hitefinder popped a round aeroconical at low altitude (hopefully after the troops had popped their square mains.
MTTB, CADS and ski packs under 28ft Utilities used the tube. CADS also used a plastic rectangular box. The payload of such systems was very poor. The cardboard tube and wooden bits was very heavy.
If ever cut away the MTTB used a CYPRES as in use with the skydiving community.
I will try and find a picture of CADs for you.
