UK: British householders in possession of "Anderson shelters" are required by law have them up and earthed by today.
A typical Anderson shelter
The Anderson shelters, designed in 1938, were personal air-raid shelters that could accommodate up to six people. They consisted of six curved galvanized corrugated steel panels, bolted together at the top, buried 4 feet deep in the soil and then covered with a minimum of 15 inches of soil above the roof. The earth banks could be planted with vegetables and flowers, that at times could be quite an appealing sight.
Anderson shelters were issued free to all householders who earned less than £250 a year, and those with a higher income were charged £7. Some 1.5 million shelters of this type were distributed from February 1939 to the outbreak of war. During the war, another 2.1 million were erected.
The Anderson shelters performed very well under blast and ground shock.
At the end of the war in Europe, all Anderson shelters were expected to be removed and local authorities began the task of reclaiming the corrugated iron. Householders who wished to keep their Anderson shelter (or more likely the valuable metal) could pay a nominal fee.
Because of the large number made and their robustness, many Anderson shelters still survive, though many have been converted into storage sheds.

MTO - Italy: Day 1 of 1 of the British Operation CORKSCREW. After an intense 20-day bombing campaign, the invasion of the Italian island of Pantelleria is met with a quick Italian surrender and no casualties.
British soldiers during Operation CORKSCREW
An earlier plan in late 1940 to occupy the island of Pantelleria, between Sicily and Tunisia, was called Operation WORKSHOP. It was aborted when the Luftwaffe strengthened the Axis air threat in the region. Radar installations and the airfield on the island remained a real threat in the MTO, especially to the planned invasion of Sicily. The Italian garrison on the island was 12,000 strong in well-entrenched pillboxes with 21 gun batteries.
It was decided to attempt to force the island into submission by aerial and naval bombardment alone. Failing that, an amphibious invasion was planned. The 20-day naval and aerial bombardment of the island began on 03 May 43, with each attack increasing steadily in intensity. A total of 6,202 tons of bombs were dropped on the island.
Two demands for the garrison to surrender went unanswered and, on 11 June, the amphibious assault went ahead. About an hour before the landing craft reached the beaches, the accompanying ships opened fire. Unknown to the British attackers, the commander of the garrison on Pantelleria had sought permission to surrender from Rome the previous evening and received it just that morning. As British Commandos first landed, the Italians surrendered.
This is the first known time in WWII that a surrender had been achieved through bombing alone.
Churchill later records in his memoirs that the only British casualty was a man bitten by a mule.
An assessment by the British reported that the defenses on the island had been reduced to 47% effectiveness by the combing campaign.
The Italian garrisons on other nearby islands (Lampedusa and Linosa) quickly fell. This cleared the way for the invasion of Sicily a month later on 09 Jul 43.
