I'm having a LYS-LHR-SEA flight next Wednesday, and shall arrive at LHR early in the morning (7.40 am), and depart only around 2 pm. Which leaves me with a few hours to spot, and practise with my brand new 300D (rhaa, money out of my bank account !).
Anyway, if it is not raining, I shall be at Hatton Cross for a few hours (probably 3 or 4 hours only - would not want to miss the second flight ). Any LHR or British spotter will be there that day ?
