Sorry I got a out of order here Pintu. Wanted to slip this one in A Zeppelin over London From 1915 to 1917, there existed a very real threat of a bombing campaign on mainland Britain as the giant German airships drifted silently and menacingly across the English Channel and the North Sea to deliver their deadly cargo on the towns and cities of the east coast. Countermeasures were soon put into action as powerful searchlights picked out the Zeppelins for the anti-aircraft batteries and RFC pilots to pour their unrelenting fire into the raiders, sometimes with little effect, sometimes with catastrophic results. Here, 2nd Lieutenant Brandons BE.2 climbs for position, its exhaust pipes aglow in the dark, whilst flak bursts all around the massive bulk of the L.33 as she passes over the east end of London on the night of 23 / 24th September 1916.

The B-25 Mitchell Bound for Tokyo Lieutenant Colonel Jimmy Doolittle launches his B-25 Mitchell from the heaving deck of the carrier USS Hornet on the morning of 18 April, 1942. Leading a sixteen-bomber force on their long distance one - way mission, the Doolittle Raiders completed the first strike at the heart of Imperial Japan since the infamous attack on Pearl Harbor four months earlier. Together, they completed one of the most audacious air raids in aviation history.

Sailor that's are the nice presentation to the historical events in the aviation history, kudos for that, and dear friend no need to sorry about , I always eagerly look forward for your help. Regards
