I just wanted to know if anyone knew why there was a Song 757 in JAX
today between around 5, 5:30pm. At first I thought it was a sub for one of the atl flights, but both the 4 and 6 pm arrivals were 763s. Odd thing is that it landed and then about 5 to 10 mins later took off again. I figured maybe it was a diversion or something, but I couldn't find it on flytecomm, flightaware, or delta.com.
