Pleidies & Air Canada 787 Dreamliner

Whilst imaging the Pleidies my shot was rudely gatecrashed by an aircraft..

This is quite normal, with the nav lights drawing across my shots, however this time the underside strobe has lit up the back of the aircraft.

This is Air Canada Boeing 787-8 Dreamliner (C-GHQY) from Toronto around 12mins from landing at LHR.

I've never had a capture quite like this before...
