I'd say its assignment to 8th AF is of interest: I'd expect it to be assigned to a Bombardment Wing/Group if supporting a TDY.
Incidentally, to explain the 'Wiesbaden' confusion: if an aircraft goes u/s away from base, it is usually handed over to the maintenance organization where it is physically located for rectification. This gives the impression when reading record cards, that it has been 'assigned'. However in cases where transient maintenance is being performed, the aircraft's status is changed on the record card. Thus in the case above, it goes from being 'CC' (combat ready) with 8th AF to 'RT' (transient maint) at Wiesbaden and also one in a similar way to another occurrence in 1951, but this time at Ernest Harmon AFB.
So it would seem that someone didn't spot the subtle change in aircraft status when previously interpreting the record card. It can be a challenge!
