I remember many years ago a chum on my Sqn getting just a little too enthusiastic with dive bombing Filfla Rock (just off Malta) and both engines of this Canberra flamed out due to negative G. He glided back to Luqa airfield and had to hand pump the undercarriage down. The main wheels came down at about 10 feet and he held the nose up whilst still frantically pumping until the nose leg locked down. He got a good show for that and a b*llocking for flaming out the engines.
