Glad you reported it but there is a plant research station (Jealott's Hill) with extensive greehouses (and very powerful lighting) just about the point you mention.
Barcoding aircraft, now that is an interesting idea! Perhaps we could use it instead of radar; just have a reader twirling around at LHR instead of pumping out all those electrons? Just think, anyone who didn't get scanned could go to Customer Services in a separate holding area until they were sorted out! We could even deduct the route charges from your debit card immediately after shutdown.
I really like this idea; must progress it further!
