Bull readies for taxy-out

An airman takes a quick photo of a Jaguar IS, just before the pilot taxies from the dispersal area. The airmen appears to be focusing the camera lens right below the air intake. Any indication why? The Jaguar being photographed carries the yellow & red chequer board markings on the inlet, which indicates the aircraft belongs to No.14 Bulls Squadron. The Jaguar parked next belongs to 5 Squadron, indicating that the location is Ambala AFS as both squadrons are stationed there.
