From a friend:
Until later in the week starting Monday 9 March, at least seven F-15's from Oregon ANG's 173 FW are deployed to Tucson IAP, Az. Serials concerned include F-15D's 79-0008 and 78-0563 with F-15C's 78-0478, 78-0547 (commander's a/c) 79-0077, 78-0493 and 79-0081.
If you're in the area, they appear to be flying quite often.
Hans.
