Yes. I read where this flight is STS-113, and the problems with Apollo 13, superstition has reared its head. Especially since both flights have had to replace crew members due to illness.

Superstition must be big in NASA, since on both missions, the crew patches use roman numerals rather than use the number 13.

Maybe the problem is Roman numerals. Sacrifice the chicken, burn the candle and launch the darned thing.
