I, like most, have the greatest respect for the AAIB, their work and understand the importance of a detailed investigation. However, I must confess I too wondered why it took so long to get BHX open again.
All we can reasonably ask of the investigation teams and the airport, is that they conduct as thorough investigation as is required in as short of time as possible and be conscious of the considerable commercial impact it has on other airport users. With that reassurance I don't think we can ask more of them.
