Different circumstances I know but one wonders whether Barnes Wallis' bouncing bomb would ever have made it off the drawing board if subjected to similarly anachronistic assumptions and raw exposure to the press and poo-pooing armchair experts:
- High risk strategy.
- Dependent on unproven technology.
- Involved use of radical tactics.
- Dismal track record of development trials.
- Inadequate historical data.
- Required expensive airframe modifications.
- Required extensive and risky crew training.
- Diverted vital resources (funding, R&D, frontline aircraft, skilled personnel and production facilities) from main effort.
- Limited (almost one-off) short-term application.
- Extremely hazardous in operation resulting in losses of entire aircrews.
