John Downman is a standard call but runaway cradles are, thankfully, not a standard event; they can kill.) Operators are trained not to attempt to stop a runaway lineset but rather to warn others and safely escape. The reason for this is that it is unlikely that they will be able to stop it, and very likely that they will burn their hands or be lifted by the lineset, potentially injuring themselves on structure above and/or from a subsequent fall. Furthermore, this might position the operator in the path of the batten, arbor, or sandbag as they accelerate downward. Spreader plates are 	Fly system

Counterweight system loading procedure. When loading a batten, or arbor in a counterweight system, it is imperative to control the balance of a set. The lineset should be balanced before loading begins, then the batten flown in, the set added, and then the counterweight added from the loading bridge. The specific order is important because it keeps the set from being unbalanced in a 	Fly system

When it is batten-heavy (after the set is added, but before the counterweights) the arbor does not have anywhere to run away to as it is already at its grid stop (the upper end of the track). In cases where the set is too tall for the batten to be all the way in, it should be kept as far down as possible. It is always best to add the load in pieces as small as practical and counterweight them one at a time so the system can never get too out of 	Fly system

Fly system A fly system, or theatrical rigging system, is a system of rope lines, blocks (pulleys), counterweights and related devices within a theater that enables a stage crew to fly (hoist) quickly, quietly and safely components such as curtains, lights, scenery, stage effects and, sometimes, people. Systems are typically designed to fly components between clear view of the audience and out of view, into the large opening, known as the fly loft, above the stage. Fly systems are often used in conjunction with other theatre systems	Fly system

Downman is thought to have been born near Ruabon, Denbighshire, the son of Francis Downman, attorney, of St Neots, and Charlotte (née Goodsend, eldest daughter of the private secretary to George I); his grandfather, Hugh Downman (1672–1729), had been the master of the House of Ordnance at Sheerness. The Downman family is usually known as a Devonshire one, but the exact connexion between the artist and the Devonshire branch has not been traced. He was educated first at Chester, then at Liverpool	John Downman

Downman set off in 1773 with Joseph Wright of Derby, a pregnant Ann Wright and Richard Hurleston for Italy. Their ship took shelter for three weeks in Nice before they completed their outward voyage in Livorno in Italy in February 1774. Downman returned to Britain in 1775. He settled down for a while in Cambridge (1777), eventually coming to London, where he contributed to various art exhibitions. In 1804 he moved to the village of West Malling in Kent. In 1806, Downman 	John Downman

He left a large collection of his paintings and drawings to his daughter. He was also the father of Sir Edwin Downman. He exhibited 148 works in the Royal Academy between 1769 and 1819, mainly portraits, but often fancy subjects, such as 'Rosalind,' painted for the Shakespeare Gallery; 'The Death of Lucretia; The Priestess of 	John Downman

His first work at the Royal Academy (1769) was A small portrait in oil",' and the last (1819), "A late Princess personifying Peace crowning the glory of England reflected on Europe, 1815". In 1884 the trustees of the British Museum acquired, by purchase, a volume containing numerous coloured drawings by Downman, among which were several portraits, now separately mounted. He also left several volumes of exquisite drawings, executed in red and black chalk, of which Ralph Neville Grenville  published a catalogue (Taunton, 1865). He also painted some miniature portraits. Engravings were also made by Bartolozzi and others. Many of his portraits have attached to them remarks of considerable importance respecting the persons represented.
