I saw a "big one" once at Ilford. Very quickly but it left an orange trail that dissipated like sparks after a fire work and some whitish smoking trail. Lasted probably not even one second but the trail stayed for about 4 or 5s until it disappeared in turn. I think it's just a matter of looking up at the right spot at the right time. These things happen too fast. But I don't mind. I'd rather still see small ones occasionaly than stirring at a big one for days coming right at us.
