Yep. 1991 at Diego Garcia. No precision approach there, so the AF brought in a mobile PAR that we had been using. One night in heavy rain, one of our BUFFs ran off the slick coral runway and shut the runway down. We still had 3 or 4 jets airborne. The parallel taxiway was the old runway. The PAR guys re-calibrated the PAR for the taxiway in record time and brought the rest of the jets in on the taxiway. Those PAR guys were heroes that night. I think they all got well deserved medals for saving the day (night)!
