Myrtle Avenue Heathrow

[Fife and herts]

Hi myself and wife are new here and we’re no experts just lovers of aviation . We would like to set off early in the morning to do our first plane spotting and a little unsure if going tomorrow is correct as in runway they will use . We think it’s 27L which would be correct but just wandered if anyone with good knowledge could confirm this . Many thanks and again I’m a lover of aviation and it puts a smile on our faces that’s all . Thankyou
