Reminds me of the story I heard from Brunei. The army wanted an RAF Wessex to carry 18 troops for an op. The RAF pilot said, "can't be done, too heavy". An RN Wessex pilot said he'd give it a go, loaded 18, pulled to the hover, re-landed. "See," said the RAF, "can't be done" The RN pilot radio'd, "I'll take three more but thats your lot!!"
