of the way the designations and launch manifest work, the mission numbered STS-13 might not have actually been the 13th to launch as was common throughout the shuttle program; indeed it turned out to be the eleventh. One of the reasons for this was when a launch had to be scrubbed, which delayed its mission. NASA said in a 2016 news article it was due to a much higher frequency of planned launches (pre-Challenger disaster). As it was, the Shuttle program did have a disaster on its one-hundred and thirteenth mission going by date of launch, which was STS-107. The actual mission STS-113 was successful, and had actually launched earlier due to the nature of the launch manifest. Omission of 13th rooms, floors and decks Many ships, including cruise liners have omitted having a 13th deck due to triskaidekaphobia. Instead, the decks are numbered up to 12 and skip straight to number 14. Hotels, buildings and elevator manufacturers have also avoided using the number 13 for rooms and floors based on triskaidekaphobia. Famous people with triskaidekaphobia Arnold Schoenberg Franklin D.

In China, Taiwan, Singapore, Japan, Korea, and Vietnam, as well as in some other East Asian and South East Asian countries, it is not uncommon for buildings (including offices, apartments, hotels) to omit floors with numbers that include the digit 4, and Finnish mobile phone manufacturer Nokia's 1xxx-9xxx series of mobile phones does not include any model numbers beginning with a 4 (except Series 40, Nokia 3410 and Nokia 4.2). This originates from Classical Chinese, in which the pronunciation of the word for "four" (四, sì in Mandarin) is very similar to that of the word for "death" (死, sǐ in Mandarin), and remains so in the other countries' Sino-Xenic vocabulary (Korean sa for both; Japanese shi for both; Vietnamese tứ "four" vs. tử "death"). Friday the 13th (Paraskevidekatriaphobia or Friggatriskaidekaphobia) is considered to be a day of bad luck in a number of western cultures. In Greece and some areas of Latin America, Tuesday the 13th is similarly considered unlucky. Number 17 (Heptadecaphobia). In Italy, perhaps because in Roman numerals 17 is written XVII, which can be rearranged to VIXI, which in Latin means "I have lived" but can be a euphemism for "I am dead." In Italy, some planes have no row 17 and
