Thesis:

Modern day airship travel would have been completely different if the Hindenburg disaster had not taken place and halted progression. Airship travel was quickly gaining popularity especially throughout the aviation community. After the accident, airship travel dwindled due to public opinion. Modern day airship travel is not as appealing as it was before the Hindenburg disaster.

Include this source somehow:
