This sharpish little jump could be attributed to a number of things, with a possible news release to follow, as you said Bull. Insider trading is illegal, but it is so very difficult to keep all secrets from everyone.

Maybe someone witnessed a truck pulling up outside MJP's Christchurch office, carrying a large wooden box with a UK made 6 cylinder engine. Maybe someone poked their head through the new tent flight test fascility and liking what they saw.
