When on my way back to the staff car park at LHR yesterday evening, I saw BA engineers and ground crew towing AF around Eastside engineering base.
She was being towed from the hangar she had been in round to the usual parking area where the other 4 Concordes are! BA are being extremely careful with her - I counted 15 ground crew walking along with her checking the tarmac and 2 in the tug!!
Good luck to her today (like she needs it)!
