"Simmer down.......we are trained in First Aid only"
I think you put yourself down. Cabin crew are trained in a multitude of skills. What will be next, the firemen union suggesting you take a 3 week course in firefighting. The cabin crew SEP will take about a month to complete.
Slightly aside from this issue my doc advised my wife that he could not write a fit to fly certificate when she was pregnant because the BMA have told him not to due to risk of liability. Maybe this issue is to do with doctors being asked to treat sick passengers on board aircraft and the perceived liability problems with doing so.
