De-icing ops run out of T4 with only 2 out of 6 rigs working. Rigs had to return to T4 to refill causing massive delays (allegedly). Solution........sue the pilots for ruining the BA brand (my dog left a pile of BA brand on the common this morning!).
T5 has its own de icing fill up facility near the end of 09R, I guess along with a lot of other things in T5 it still isn't ready, BAA for you!
Seemed clear enough to me ... and do the de-icers have to share the taxyway with aircraft to get from T4 to T5? Or did someone think it through and build a service road?
There is a road that has been built for Cargo to get round to T5, it runs from the end of cargo around 09R into T5 that way. Not sure if anyone else is allowed to use it.
