I would love to be on a 09L departure, in 22 years flying from LHR, I have never been on one. I did see three heavies depart off 09L last year during snow days when the Southern runway was closed. Just ignore Cassandra and those who specialise in 100% negative one liners, they don't have anything worth contributing beyond a glass half empty view. (and smashed on the floor and bombed by a drone before being ground to dust and scattered to the four winds. Bit negative, wonder how some people face getting out of bed?)
