Problem: The United States Navy (USN) hoped to use the V-1710 in its rigid airships USS Akron (ZRS-4) and USS Macon (ZRS-5), but both were equipped with German-built Maybach VL-2 engines as the V-1710 was still in testing when the Macon was lost in February 1935 (the Akron having been lost in April 1933). The USAAC purchased its first V-1710 in December 1932. The Great Depression slowed development, and it was not until December 14, 1936 that the engine next flew in the Consolidated XA-11A testbed. The V-1710-C6 successfully completed the USAAC 150 hour Type certificate on April 23, 1937 at , the first engine of any type to do so. The engine was then offered to aircraft manufacturers where it powered the prototype Curtiss XP-37s. All entrants in the new pursuit competition were designed around it, powering the Lockheed P-38, Bell P-39 and Curtiss P-40. When war British Purchasing Commission asked North American Aviation to build the P-40 under license, NAA instead proposed their own improved aircraft design, using the V-1710 in their North American P-51 Mustang.

Problem: The Bears hosted the Jacksonville Jaguars in week six, their first game since a 41-3 Bears victory in 2012 and the first in Chicago since the Bears won 23-10 in 2008. In six games, the Bears led the series 4-2. Jeff Joniak wrote the offense should employ a run-based attack with Jordan Howard, interspersed with short passes by Brian Hoyer. The Bears led the league in passes of at least four yards and rushes of at least six yards on first down. Defensively, the Bears needed to disrupt quarterback Blake Bortles' rhythm; when his consistency is broken, he is prone to throwing interceptions. To do so, Joniak stated the Bears should apply a pass rush as "young quarterbacks don't like pressure." Meanwhile, Jacksonville's rushing attack, while not seeing much action, was spearheaded by T. J. Yeldon and Chris Ivory. Joniak also believed a crucial factor of the game is the battle on third down, where the Jaguars had struggled during the season. Of his six interceptions in 2016, Bortles had thrown four on third down, while the Jaguars were ranked 29th and 32nd on third down defense and offense, respectively. The Bears escaped a 7-0 deficit when Tracy Porter intercepted Bortles in the endzone to stop an 84-yard drive, instead taking a three-point lead on Connor Barth's 36-yard field goal in the second quarter. After the Jaguars punted, the Bears drove 86 yards and scored on Jordan Howard's one-yard touchdown run. By halftime, the Bears led 10-0, the first time they had shut out an opponent in the first half since 2012 against the Lions. The first five drives of the second half failed to result in a score, instead ending with punts before the Bears widened the margin to 13 points with Barth kicking a 24-yard field goal. The Jaguars responded with Ivory's one-yard touchdown run in the fourth quarter; after a Chicago punt, they reclaimed possession when Willie Young stripped the ball from Bortles and Akiem Hicks recovered the fumble. Barth kicked a 32-yard field goal, but Jacksonville's Jason Myers narrowed the margin to six points with a 30-yard field goal. The Bears eventually punted again and four plays into the Jaguars' following drive, Bortles threw a pass to Arrelious Benn, who took advantage of Porter slipping to score on a 51-yard play and give the Jaguars the lead. With 2:49 left in the game, Brian Hoyer attempted to lead the Bears downfield, reaching as far as the Jaguars' 44-yard line when a holding penalty on Howard forced the Bears back. On fourth down, Hoyer's pass for Cameron Meredith was broken up by Jalen Ramsey and the Jaguars ran out the clock to claim the 17-16 win. The Bears dropped to 1-5, their worst start since 2004, and their 16th home loss in the last 20 games. The loss was also the first time the Bears lost despite a 13-point lead entering the fourth quarter since a 1999 loss to the Seattle Seahawks.

Problem: The Bears' seventh game was an NFC duel with the Redskins at home. In the first quarter, the Bears took a sudden lead as CB D.J. Moore returned an interception 54 yards for a touchdown. However, their defense was broken down as QB Donovan McNabb completed a 24-yard TD pass to WR Santana Moss. In the second quarter, they trailed after kicker Graham Gano nailed a 46-yard field goal. The Bears' offense broke through as QB Jay Cutler got a 9-yard TD pass to WR Johnny Knox, but was closed off in the third quarter as Cutler's pass was intercepted by DeAngelo Hall and returned 92 yards for a touchdown. With the loss, Chicago fell to 4-3 heading into their bye week.
