I even forgot one of Spantax´ accidents: the midair collision of one of their CV990s with an IB DC9 over France in 1973 in which all 68 on board the IB craft perished. That leaves us with accidents in 1965, 1970, 1970, 1972, 1972, 1973 and 1982 - semantics aside (and I gladly concede your mastering of the English language is certainly superior to mine), 5 accidents in 3 years, 6 accidents in 8 years, 7 accidents in 17 years - whichever way you look at it, it´s an impressive streak (of whatever).
And on your repeated statements that Spantax operated for 28 years (29 actually, they were founded in 1959, not 1960) - I just read Mr. Bay Wright´s obituary (http://www.el-mundo.es/2000/10/02/opinion/02N0036.html
The founder of Spantax continued to be a commercial pilot at Iberia until 1967; can you imagine his airline Spanish Air Taxis can have been more than a hobby before that?
This article, which is written very positively toward the deceased and his company, characterises Spantax as suffering "for years of slow agony until its eventual disappearance" since at least 1979.
Your way of looking at Spantax as a whole is misleading, just like calculating an average consumption of alcohol over a whole population, including babies, pregnant women, 80 year olds etc.
>>>though they were pretty big in the UK as well!
I believe you´re right, after the German tour operators cancelled their contracts with them they had to sell their capacity to someone else; and since the British customer is less demanding than the German one (generally speaking), Spantax´ routes were shifted from Germany to the UK to a great extent in the eighties.
