Lack of rigorous T&E results in poor procurement
As with the Army's Snatch LR debacle, if you want clear evidence that rigorous T&E is needed then investigate the way the last EFT/Bulldog replacement was conducted. Boscombe had little to zero input in the selection process. Flight "testing" was left to AEF pilots and QFIs. The result was an underpowered, high drag, low payload and barely aerobatic machine that is near invisible on the standard British day to external observers. Couple this with a poor canopy design that obscures lookout for pitching and turning manoeuvres, no go forward harness and a "jettison" handle that does not do as it's title suggests, and the results are tragic. 6 deaths in 2009 and 4 flying machines destroyed. Thankfully qinetic did get involved post accidents. But the machine remains problematic in service - just read the last years worth of DASORS. The bolt on solutions are not working as first Thot.
