B-29 BOMBS OVER BURMA-Tons of bombs speckle the sky over Rangoon, Burma, as they spew from tile yawning bomb bays of Twentieth Bomber Command Superfortresses. The target of this daylight attack by Brig. Gen. Roger M. Ramey's India-based airmen was a large Japanese supply depot near the Mingaladon Air Field near Rangoon. Returning flyers declared it a "perfect mission" from the standpoint of weather and observed results of bombs on the target.
Grant, as far as I know, the forward, underside aerial is the VHF antenna, later replaced by a 'whip' antenna, and then later still moved to the top of the fuselage. It's sometimes confused with the aerials and equipment carried by the 101 Sqn aircraft, on jamming ops.
The rear aerial is, I believe the IFF antenna, replacing the original wires running from tail fins to a point just below and slightly aft of the mid-upper turret. Just outboard of this, and I think only just visible, would be the 'Lorenz' beam approach antenna, running fore and aft, and looking rather like a towel rail.
