Hope they clear up a few things.....
The term Union Jack possibly dates from Queen Anne's time (reigned 1702-14), but its origin is uncertain. It may come from the 'jack-et' of the English or Scottish soldiers; or from the name of James I who originated the first union in 1603, in either its Latin or French form Jacobus or Jacques; or, as 'jack' once meant small, the name may be derived from a royal proclamation issued by Charles II that the Union Flag should be flown only by ships of the Royal Navy as a jack, a small flag at the bowsprit.
A careful examination of the flag shows that it does not have reflectional symmetry, due to the slight pinwheeling of St. Patrick's cross, which is technically called the counterchange of saltires. Thus, it has a right side and a wrong side up. To fly the flag the correct way up, the broad portion of the white cross of St Andrew should be above the red band of St Patrick (and the thin white portion below) in the upper hoist canton (the corner at the top nearest to the flag-pole), giving the Scottish symbol precedence over the Irish symbol. This is expressed by the mnemonic: wide white top, and the phrase: broad side up. Traditionally
, flying a flag upside down is understood as a distress signal, however this slight asymmetry is too small to be seen reliably at any distance, so the Union Flag is never used in this way. It is, however, practicable with the various ensigns that are actually flown by British naval, commercial, and pleasure craft.
