First and foremost, you can only feel gutted for Leon Haslam. He is more than British, he is the local lad that grew up close to Donington Park. A win here would have meant more to him than anyone else. To lose it on the final corner through no fault of his own is heartbreaking for even the stoniest of viewers.
Attention thus turns to who is at fault then. Some will say Melandri shouldn't have forced the point with a fairly rash attempt at a pass into the final corner, while others will point the finger at Rea for diving for a gap that was always going to close.
However, racing incidents are often defined by the factors surrounding it. If Melandri hadn't made the move, Rea wouldn't have attempted to follow through. The pass wasn't clean, but contact was as much about Haslam - no doubt startled by Melandri - turning in not expecting a Honda to be there as it was Rea leaning on him.
Of course, Rea didn't intend to knock Haslam off and, technically speaking, he was alongside enough for it to be classed as a racing incident... which is why I was call it just that. Not that 'technically speaking ' will make the Haslam family, or BMW, feel any better.
Been a bit distracted by a thrilling Spanish Grand Prix (well done Williams!), but other notable results in that Supersport race included Glen Richards's ride to fifth, an impressive result for the wild-card entrant.
On the other side of the scale, Fabien Foret's title charge is unraveling by the race as he could only manage a nondescript run to tenth. The man was the joint leader of the championship before Monza, but is now 26 points adrift.
After several near misses, not least last week at Monza, Sam Lowes can finally call himself a World Supersport race winner after a mature ride to victory here at Donington Park.
An emotional moment for the youngster, Lowes shrugged off a disappointing start to grab the lead on lap eight and didn't look back - which is just as well because Sofuoglu was beginning to put the pressure on.
A popular win in front of his home fans, could this be the win that kick starts the Lowes title campaign...?
Without meaning to gloat, didn't I say it'd be a Melandri, Haslam, Sykes podium...?
It's looked in the offing for some races but BMW can finally call themselves WSBK race winners following Marco Melandri's win in race one.
An exciting and incredibly tense race, though it was a little disappointing from a British perspective, Melandri was in fairly imperious form, where as Haslam was just as quick - if not quicker - but too error-strewn.
