BA 757 was G-BPED, so def a 757! Maybe something to do with the schedules changing on Sunday and an extra a/c required? As I type, KLM 737-900 just touched down, also very rare, but then the first KLM was u/s! Apparently the mexican presidential team asked for all helicopter ops to stop whilst he arrives, this will be interesting! A Kittyhawk due in around same time also.
