20070902H1 Aircraft 42RF Felix flight 2007
***per report..... "Upon penetration of the eyewall, at 10,000 ft, the aircraft was pelted with hail, encountered constant cloud-to-cloud lightning, and an updraft downdraft couplet that caused the accelerometers to read +4G/-4G, higher than safe operations allow, so the decision was made to abort the mission".....***
