That seems unlikely to me. The RC field is over 12 miles from the nearest fire location, and 8 miles outside the boundary of the TFR.

The RC field would've received a grounding notice from the FAA, like any other private / civilian field.

Emergency areas are cleared for emergency flights only and their airspace is restricted, even news copters cannot go into that space and many of them were fined and even licenses were revoked when they violated the restrictions.
