Sounds you NEVER want to hear
I declared an emergency with the MacDill tower. I also cleared the two students to break away and head straight to the base and get on the ground ASAP; I didn’t want to close the runway with them still in the air. I directed the IP in #3 to ‘chase’ me, which meant he would be alongside to observe that my gear ‘blew down’, to back me up on the checklist, and to make sure I didn’t get ‘behind the aircraft’ as I handled this emergency.
