The date of this sports related plane crash is quite curious, so is the name of the Airlines. At the time, it was also one of the worst plane crashes to date. Let us begin with the Gematria of the Airlines, and the date of the crash.
- Trans-Canada = 2+9+1+5+1+3+1+5+1+4+1 = 33
- Airlines = 1+9+9+3+9+5+5+1 = 42
- 12/9/1956 = 1+2+9+1+9+5+6 = 33
- 12/9/56 = 12+9+56 = 77
December 9 is the 343rd day of the year, and 344th on leap years, which 1956 was.
From the information above, it is interesting that it was cleared for runway "RED 44" and last made a radio transmission as it passed 'HOPE'.
- Hope = 8+15+16+5 = 44
- Kill 11+9+12+12 = 44
All in all, I doubt very much this was an accident. This crash claimed the lives of five Canadian Football All-Stars, and the lives of many other related personnel. In total, there were 62 deaths, matching the Gematria of the word 'Mason'.
