GDI had just failed a Mammoth tank rush and we were getting ready to send a flame rush when suddenly someone on our team said (using F2) "OMFG look at that!! there is a Mammoth tank stuck on top of the Air strip" GDI loled back and said "let me see" so then we got our snipers ready and got ready to send the flame rush, sure enought there was a load of GDI infantry standing at the top looking for the tank and before they know what was going on we had sent the flame tanks and sniped most of there men (I'v seen this used before but it doesnt always work)

BTW
I once did see a Mammoth tank in the Sky over the Airstrip. It hung there for 35 minutes, then in the last 2 minutes fell. It had hardly any health but we were able to use it. I never did find out why....It was on that very same map.

We couldnt have both been playing at the same time because there was no mammoth tank but It made GDI look
