Trident at LHR (Engineering Base)
The aircraft is preserved with most of its internal fittings. It was used for towing practice but alas it cannot accomodate the modern towbarless tractors. I believe at this time it is not used by conventional tractors either as there is some concern about the undercarriage. As space is money i.e. parking fees it is rumoured that it will not be long before BA wants it off the base and ultimately off LHR.
