"Lineing up in a 757 on 24L this morning. As we were cleared for take off, bird van asked tower if he could do a run on 24L after our departure.He had just done 24R. I did think about not going for a second! Then again the other, light blue, 757 infront of us had probably done the job. Why did the van bother?"
I presume you are refering to the ops vehicle 'Scarecrow. Whilst not employed by the airport, I am given to understand that runways checks are performed by various operations personnel using callsigns 'Checker', 'Ops' and 'Scarecrow'. The fact that the 'run' was being undertaken by 'Scarecrow' does not necessarily mean that it was a birdscaring exercise and it was in fact more likely to have been a routine runway surface inspection.
Hope this helps.
