You train and train and train and then you train some more. You could try selecting the letters and using the content aware fill in Photoshop and cleaning the rest with the patch tool. Depending on the lighting and the movement of the blimp you'll need multiple clean plates. If you have Mocha Pro you could try the remove module.
