LFCDA-LFB Heavy fire Rescue tenders
The 1990s saw a new breed of fire rescue tenders, large and small, introduced into the London Fire Brigade. The heavy rescue unit carried a comprehensive range of cutting and spreading equipment, a larger crew, breathing apparatus and chemical protection suits. The light unit, whilst having lifting and spreading equipment, did not have the same scoop of equipment and carried a smaller crew. The picture shows the open compartments on one side of a heavy rescue unit

Bottlenose dolphins - blowing air bubbles underwater
Bottlenose dolphins - blowing air bubbles underwater (Tursiops truncatus). Distribution: Worldwide except polar regions. Complex play / creative behaviour: dolphins often play with the bubbles or rings of air they create, both visually and by using sonar. They appear to enjoy biting the vortex rings, so that these burst into many seperate normal bubbles, which then rise more rapidly to the surface. They also play games, diving through the bubble rings for fun!

Underwater theodolite off the coast of Malta
Diver using a theodolite to survey the best location for an inflatable house which was anchored to the seabed, some 50 feet deep, in Paradise Bay, off the coast of Malta. He is writing something down on a waterproof clipboard. It was equipped with lighting, telephone and immersion heaters with which the inhabitants could make hot drinks. It was constructed by teams of engineers and diving enthusiasts from Imperial College of Science and Technology and Enfield College of Technology. It was 9ft long and 6ft wide, constructed from rubberised material on a steel frame, and weighed around 500 lb. The team leader was David Baume who hoped it would be the first of a series of low cost underwater living spaces from which scientists could explore the seas. David and some other team members were able to spend a night 30 feet below the surface. The following day a severe storm caused the house to collapse.
