Bradley wrote about this in his introduction of using the PSSR (PSSI) rate to progress the Arisolar. He called it, "One of the worst accidents in commercial aviation history." He gave the slightly different details of 19:32 UT (2:02 later than the time I have), 36N00 111W49 (I found different coordinates).

June 30, 1956, 10:30 AM, 36N10.5, 111W40. 128 died.

The Capsolar daily timing was adequate enough above, and the CanQ nailed it with transiting Mars on the CanQ MC. Not using the CanQ, this Mars is something Bradley thought missing, and was happy to find it in the PSSI Arisolar.

Checking mean rate in addition to the apparent rate Bradley used (and using my estimation method that may be a few minutes off), I get confirmation of the angular Mars he loved from the Arisolar PSSI:

4°07' Can s Uranus
5°04' Lib s Neptune
5°18' Cap s Mars
5°41' Cap Arisolar PSSI Asc
6°59' Can t Uranus
