Another serious incident again yesterday. I fail to understand how a pilot could depart with a C210 with 6 people on board (incl foreign pilot), 5 hours of fuel and 30 C temperature
. He lost height after take off, but could control the aircraft in the last minute. He opted to return. He was so shocked that he forgot his undercarriage. ATC noticed it in the last minute and warned pilot. He did go-around and landed safely. At the end, the group departed again in 2 C210's
