The night before the crash he told me that he had been ordered to drive the bus and when he complained that the bus was'nt up to it he was threatened with the "failing to comply" charge.
That would be the SEngO then? You will know that the rumour mill ran and ran about various aspects of that bus but nothing came out at the inquiry except wrong place, wrong driver. In other words: it should not have been on that road; blame the navigator or the driver, not the vehicle.
PM me with your email address and I will send you a photo of the memorial.
